Abstract:
We characterized the magnetocrystalline anisotropy of a novel intermetallic
compound, SmFe 7 , by means of torque measurement. Single crystal of SmFe 7 was
grown by the self-flux method using Sm as a flux. From an analysis of the torque curves in the (001) and (100) planes using the least mean squares method, we found that the
tetragonal anisotropy constants K 1 , K 2 and K 3 of SmFe 7 are -8.7±0.4 (×10 7 erg/cm 3 ),
1.4±0.3 (×10 7 erg/cm 3 ), and -2.7±0.1 (×10 6 erg/cm 3 ) at 293 K, respectively. The
reliability of these values was confirmed using the results of magnetization measurements. The huge magnetocrystalline anisotropy of SmFe 7 is superior to that of Nd 2 Fe 14 B. SmFe 7 appears to be a promising host material for a
high-performance hard magnet.
