Abstract

We report the observation of superconductivity in compacted, high purity platinum powder of average grain size 2μm. The transition into the superconducting state was found by measuring resistivity and ac susceptibility as well as dc magnetization. The transition temperature TC strongly depends on the compression of the powder; we found 0.62TC1.38mK for packing fractions of 0.8f0.5, respectively. The corresponding critical magnetic fields are 6.6BC(0)67μT.

APS and CERN Sign Open Access Agreement for SCOAP3

APS and CERN, the host organization of SCOAP3 (Sponsoring Consortium for Open Access Publishing in Particle Physics), have signed an agreement to make the high-energy physics (HEP) articles published in three leading APS journals open access beginning January 1, 2018. This agreement acts to support the publishing of open access content for wider benefit of the HEP community.
