Structural Behavior of ZnCr2S4 Spinel under Pressure
Ilias Efthimiopoulos,T. Lochbiler,Vladimir Tsurkan,Vladimir Tsurkan,Alois Loidl,V. Felea,Yuejian Wang +6 more
TL;DR: In this article, the authors performed X-ray diffraction and Raman spectroscopic studies on the ZnCr2S4 spinel up to 42 GPa, chosen mainly due to the similarity of Zn2+ and Cr3+ cationic radii.
Magnetic field dependence of low-energy magnons, anisotropic heat conduction, and spontaneous relaxation of magnetic domains in the cubic helimagnet Zn Cr 2 Se 4
