Abstract

We present a comprehensive investigation on anisotropic magnetic and magnetocaloric properties of the quasi-two-dimensional weak itinerant ferromagnet trigonal Cr $_{0.62}$ Te single crystals. Magnetic-anisotropy-induced satellite transition $T^*$ is observed at low fields applied parallel to the $ab$ plane below $T_c$ . The $T^*$ is featured by an anomalous magnetization downturn, similar to that in structurally related CrI $_3$ , and shows a monotonous shift towards lower temperature with increasing field. Magnetocrystalline anisotropy is also reflected in magnetic entropy change $\Delta S_M(T,H)$ and relative cooling power RCP. Given the high $T_c$ , Cr $_{0.62}$ Te crystals are materials of interest for nanofabrication in basic science and applied technology.
