An additional degree of freedom in cobalt oxides that makes them fascinating is the spin state of the Co ions, which possess six -shall electrons and can form configurations with spins =0, 1, or 2. In the prototypical member of the family, LaCoO, the ground state is believed to be insulating with the spin state =0. However, there has been a great deal of controversy over the last decades about the nature of the excited states and the phases observed at higher temperatures. The authors here approach this long-standing problem by applying ultrahigh magnetic fields reaching 133 Tesla at temperatures ranging from 2 to 120 K. Surprisingly, at magnetic fields above 100 T, they find two novel magnetic phases that are identified as spin-state crystalline states, possibly with some orbital ordering.

This study is motivated by a challenge to the third law of the thermodynamics: how does the degenerated ground state in a textbook example behave in a real compound? At very low temperatures, nature tries to preserve the basic law using small perturbations and a novel quantum state should appear. The authors here study the classic frustrated magnet BaYbZnO, a spin tetrahedron having two-fold degeneracy realized in a breathing pyrochlore lattice. They measure by inelastic neutron scattering the low-energy excitations in order to identify the effective spin Hamiltonian and macroscopic properties at very low temperatures. They demonstrate how the degeneracy of the ground state is lifted and a unique quantum state is selected.

The role of spin-orbit coupling (SOC) in 4 and 5 transition metal oxides is relatively poorly understood outside of the LS or JJ coupling limits. In this work, the importance of the intermediate regime is demonstrated through the identification of SOC as an essential feature of the collective properties in nominally orbitally quenched 5 systems. The authors probe the magnetic excitations in model system SrScOsO via inelastic neutron scattering and model the results including the effects of SOC-induced anisotropy. Experimentally determining the strengths of nearest and next-nearest neighbor interactions leads to the important discovery that the magnetic ground state is controlled by anisotropy, which would not be possible in the LS coupling limit. This indicates that SOC plays a key role in relieving frustration and promoting heightened transition temperatures in 5 double perovskites.

Magnetic phases and phase transitions in artificial spin ice, constructed from tailor-made arrays of nanomagnets, are currently subjects of great interest. The authors present measurements of the diffuse soft x-ray resonant magnetic scattering in artificial spin ice, where the moments of the magnets, arranged on the sites of the kagome lattice, are highly dynamic. Comparing experimental scattering patterns with the patterns calculated from Monte Carlo simulations based on a needle-dipole model, they show the emergence of quasi-pinch-points in the kagome ice I phase, and explain their relation to the pinch-point singularities in spin ice pyrochlores. As in the bulk pyrochlore spin ices, measurement of diffuse scattering from artificial kagome spin ice provides unique information on the magnetic correlations and can be applied to a number of other problems concerning nanomagnetic systems.

Magnetic tunnel junctions are under active consideration owing to their applications including the potential next generations of spin transfer torque memories. In view of the high symmetry of the magnetic properties and of the high frequency of the system eigenexcitations, out-of-plane magnetized systems are thought to enable a faster and simpler spin-torque-induced switching process than the formerly used in-plane magnetized systems. Unfortunately, the lack of high frequency and low current switching experiments have precluded, so far, the assessment of the speed potential of perpendicular anisotropy systems at low junction dimensions. By time resolving the switching and evidencing its stochastic aspects at the nanosecond-scale, the authors here demonstrate that a complex dynamics happens and persists down to small sized elements with always a very strong asymmetry between the two switching directions. The reversal is explained by the complex interplay between the spatial profile of the stray field emanating from the fixed system of the tunnel junction and the constraint that the switching is preferably initiated from the device edge.
