| 英文摘要 | The intrinsic room-temperature ferromagnetism, stability in air, and easy tunability make chromium telluride Cr3Te4 a material with great promise for application in spintronics. This study investigates the magnetic entropy change (Delta S-M) associated with critical exponents of Cr3Te4 single crystal. Temperature-dependent. Delta S-M suggests a drastic entropy change caused by the transition, the parameters of which show field-dependent power-law behaviors. Fitting the Delta S-M(T, H) parameters yields critical exponents alpha = 0.056(9), beta = 0.365(4), gamma = 1.212(3), delta= 4.318(1), and Delta = 1.562(5) for H//ab, while alpha = -0.077(3), beta = 0.369(6), gamma = 1.338(1), delta = 4.620(6), and Delta = 1.689(2) for H//c. The universality principle allows the Delta S-M (T, H) to be scaled onto a single universal curve independent of external field. The direction-dependent differing critical exponents imply anisotropic magnetic couplings in Cr3Te4, which reveal a magnetic interaction of the 3D-Ising type for H//ab while a 3D-XY one for H//c. This work is beneficial for understanding the intrinsic and anisotropic room-temperature ferromagnetism in CrxTey family. |
