Magnetic proximity effect in Pt/CoFe2O4 bilayers

Phys. Rev. Materials 2, 011401(R) (2018) - Published 12 January, 2018

The magnetic proximity effect (MPE) is an important phenomenon for spin manipulation in spintronic devices, but to this date, researchers have been unable to demonstrate MPE using spinel ferrites, a versatile class of ferrimagnetic insulators with high Curie temperatures. In this study, magnetotransport measurements on platinum-cobalt ferrite bilayers demonstrate the presence of MPE, which results in induced ferromagnetic order in the platinum films. In contrast to earlier studies, the entire structure is grown by molecular beam epitaxy, which ensures the cleanest possible interfaces. These results enable the use of spinel ferrites for spin manipulation in future spin-logic devices.

All-in-all-out magnetic domain inversion in Tb2Ir2O7 with molecular fields antiparallel to external fields

Phys. Rev. Materials 2, 011402(R) (2018) - Published 25 January, 2018

Pyrochlore iridates, Ln2Ir2O7 (Ln = lanthanide), have attracted much attention lately for their potential to host novel topological states. Because the topological states are closely linked to their unique all-in-all-out type antiferromagnetic order, it is necessary to clarify the evolution of the domain state under magnetic fields. In this study, magnetotransport measurements on Tb2Ir2O7 thin films reveal that the all-in-all-out magnetic domain inversion is induced by competing external and molecular fields. This result provides important implication on the way to detect/control the magnetic domain and promotes further efforts to utilize the topological states for electronics and spintronics applications

Elastically frustrated rehybridization: Origin of chemical order and compositional limits in InGaN quantum wells

Phys. Rev. Materials 2, 011601(R) (2018) - Published 8 January, 2018

Solid state devices based on InGaN‐alloys have revolutionized lighting applications and have resulted in huge energy savings. Here, the authors investigate the growth of single monolayer InGaN layers by well-designed growth experiments, advanced characterization, and theoretical modeling. Specifically, they show that the growth of the InGaN films is self-limited with respect to thickness and chemical composition, but shows a unique chemical ordering absent in conventional InGaN films. The origin of the self-limitation is a novel surface stabilization mechanism—elastically frustrated rehybridization. The discovery of this new mechanism not only explains the origin of the experimental observations but provides also the basis for new strategies of controlled homogeneous alloying.

Semiconducting cubic titanium nitride in the Th3P4 structure

Phys. Rev. Materials 2, 011602(R) (2018) - Published 22 January, 2018

Metastable nitrogen-rich phases are of technological interest as they may possess a range of useful electronic, optical and mechanical properties. Cubic-Ti3N4 is a long-sought-after metastable phase analogous to other M3N4 (M = tetravalent metal) compounds that were discovered in the past decade. By marrying first-principles calculations with laser-heated diamond anvil cell experiments, the authors present the first experimental discovery and characterization of cubic-Ti3N4 with high cation coordination number. The new phase is expected to exhibit excellent mechanical properties, but unlike metallic TiN, Ti3N4 is a semiconductor with a direct band gap near 0.9 eV. The thermodynamic stability and transition pathway to ambient pressure are also evaluated.

Segmental front line dynamics of randomly pinned ferroelastic domain walls

S. Puchberger, V. Soprunyuk, W. Schranz, and M. A. Carpenter

Phys. Rev. Materials 2, 013603 (2018) - Published 10 January, 2018

Dynamic mechanical analysis measurements as a function of temperature, frequency, and dynamic force amplitude are used to perform a detailed study of the domain wall motion in the ferroelastic perovskite LaAlO3. The authors focus on the creep-to-relaxation region and find that at temperatures around the domain freezing regime, where the macroscopic motion of DWs has already stopped during one period of the alternating force, segments of DWs can still overcome local barriers, even at forces below the pinning force. The present work shows that ferroelastic needle tips are ideal objects for the study of elastic strings moving in a random environment.

Growth, electrical, structural, and magnetic properties of half-Heusler CoTi1−xFexSb

S. D. Harrington, A. D. Rice, T. L. Brown-Heft, B. Bonef, A. Sharan, A. P. McFadden, J. A. Logan, M. Pendharkar, M. M. Feldman, O. Mercan, A. G. Petukhov, A. Janotti, L. Colakerol Arslan, and C. J. Palmstrøm

Phys. Rev. Materials 2, 014406 (2018) - Published 12 January, 2018

Heusler compounds are an exciting class of materials due to the diverse and tunable electronic and magnetic properties. In this work, the transition of semiconducting CoTiSb to a ferromagnet is examined in the substitutionally alloyed series of CoTi1-xFexSb and Co1-yFeyTiSb, grown by molecular beam epitaxy. The electronic band structure and magnetic moment depend strongly on Fe content and in particular the site it is substituted on. This coupled with its compatibility with other Heusler and III-V compounds and the expected half-metallic behavior in this quaternary Heusler compound system, make it promising for the development of future spintronic heterostructures and devices.

Low-temperature anomalies of a vapor deposited glass

Beatriz Seoane, Daniel R. Reid, Juan J. de Pablo, and Francesco Zamponi

Phys. Rev. Materials 2, 015602 (2018) - Published 29 January, 2018

A large variety of amorphous solids display anomalies with respect to the Debye theory at low temperatures. Two examples are the abundance of low-energy modes (the ‘boson peak’) or the anomalous scaling of the heat capacity and conductivity with temperature. Quite surprisingly, these anomalies are highly suppressed in glasses prepared by vapor deposition. In this paper, authors study numerically the particle vibrations in glasses prepared both by cooling and by vapor deposition. They observe that heterogeneous vibrations appear at temperatures below a threshold, whose position decreases roughly exponentially with the inherent-structure energy of the glass, thus explaining the experimental observations. Furthermore, this anomalous behavior seems to be related to localized defects.

A large variety of amorphous solids display anomalies with respect to the Debye theory at low temperatures. Two examples are the abundance of low-energy modes (the ‘boson peak’) or the anomalous scaling of the heat capacity and conductivity with temperature. Quite surprisingly, these anomalies are highly suppressed in glasses prepared by vapor deposition. In this paper, authors study numerically the particle vibrations in glasses prepared both by cooling and by vapor deposition. They observe that heterogeneous vibrations appear at temperatures below a threshold, whose position decreases roughly exponentially with the inherent-structure energy of the glass, thus explaining the experimental observations. Furthermore, this anomalous behavior seems to be related to localized defects.
