摘要:
Magnetization curves of the Tm2Fe17-xMnx (x=0, 0.2, 0.5, 1, 1.5) single crystals have been studied. The low-temperature easy-axis type magnetic anisotropy enhances, the critical field of the first-order magnetization process (FOMP) increases, and the value of magnetization anisotropy decreases in the Tm2Fe17-xMnx compounds with the increase in Mn content. The FOMP disappears in the compositions with x=1, 1.5. Compositional and temperature dependences of the magnetic anisotropy constants were calculated via analyzing the magnetization curves.
