Relaxation of magnetization in spinel CuCrZrS4

(Cu)tet(Cr2–xSnx)octS4–ySey Spinels: Crystal Structure, Density Functional Theory Calculations, and Magnetic Behavior

“…Thiospinels and selenospinels (X = S and X = Se, respectively) with normal spinel-type structures have generated great interest because of their pressure-induced phase transitions and magnetic and transport properties. − Spinels based on Cr have been shown to possess magnetoresistance, which refers to a change in the electrical resistance of certain materials in the presence of a magnetic field . This property has been the focus of various studies for its potential use in data storage and electronic devices. , In contrast, thiospinels and selenospinels undergo pressure-induced phase transitions toward a spinel-distorted, monoclinic structure or a LiTiO 2 -type structure. ,, In addition, CuCr 2 S 4 and CuCr 2 Se 4 are metallic and ferromagnetic with Curie temperatures ( T C ) of 380 and 420 K, respectively .…”

SYNTHESIS AND MAGNETIC PROPERTIES OF CHROMIUM-BASED Cu(Cr2-xTi x)S4 THIOSPINELS AND THEIR DEFICIENT STRUCTURES Cu1-y□yCr2-xTi xS4 OBTAINED BY COPPER EXTRACTION

“…As the cationic distribution can change when substitution occurs, the physical properties of the spinel material may strongly differ from those of the non-substituted compound. Therefore, solid solutions of thiospinels have received considerable attention for their interesting electrical and magnetic properties, which can greatly vary as a function of composition [6][7][8] .…”
