Magnetic properties of Tb-2(Fe, Cr)(17) single crystal

A Tb-2(Fe, Cr)(17) Single crystal with the Th2Ni17-type structure has been prepared by the Czochralski method and investigated by means of Laue back-r eflection, metallographic observation, x-ray diffraction and magnetic measu rements. The magnetization curves along the easy and hard directions in the temperature range from 5 K to 293 K are presented. The spontaneous magneti zation increases with increasing temperature below 300 K. A magnetohistory effect was observed below 167 K. A first-order magnetization process (FOMP) of type I was also observed below 250 K. The FOMP critical fields occur at about 5.5 T at low temperature.
