MAGNETOCRYSTALLINE ANISOTROPY OF (PR1-XSMX)2FE14B

Magnetocrystalline anisotropy of (Pr//1// minus //xSm//x)//2Fe//1//4B compounds have been studied in the temperature range 1. 5 to 290 K. The anisotropy constants K//1 and K//2 were found from modified Sucksmith-Thomson plots. In Pr//2Fe//1//4B (x equals 0) and (Pr//0//. //8//5Sm//0//. //1//5)//2Fe//1//4B, the c-axis of the tetragonal structure is the easy magnetization direction. A canting angle between the easy direction for magnetization and the crystallographic c-axis was observed for x equals 0. 30 and 0. 45. The anisotropy energy is only about 2 multiplied by 10**6 erg/cm**3 at x equals 0. 60. When x equals 0. 75, the easy direction for magnetization is in the basal plane like that observed in Sm//2Fe//1//4B (x equals 1).Materials Science, MultidisciplinaryPhysics, Condensed MatterSCI(E)EI3ARTICLEPt 2887-88854-
