AbstractA trigonal Te-rich Cr5Te8 single crystal was grown by the Te-flux method. The usual and rotating magnetocaloric effects have been investigated by measuring isothermal magnetization curves on both a single crystal and polycrystalline powder. The Curie temperature and the magnetic moment of trigonal Te-rich Cr5Te8 were determined to be 250 K and 2.03 mu(B)/Cr, respectively. The difference from the usual magnetocaloric effect, the rotating magnetocaloric effect has saturation tendency when the applied field is above the anisotropy field. The temperature, where the rotating entropy change has its maximum, decreases with increasing the magnetic field. The temperature dependence of the magnetocrystalline anisotropy is the determining factor for the rotating magnetocaloric effect. (C) 2017 Elsevier B.V.
