Abstract :
The magnetocrystalline anisotropy of bunched single crystals of SmFe11-xCoxHy (x = 0, 1, 2, 3, y < 1) was studied using a fitting procedure of magnetization curves. The anisotropy constants obtained were compared to those of the corresponding nonhydrided compounds. A drastic change in anisotropy as a result of hydrogenation was found which is discussed in terms of a point charge model. An unexpectedly high room temperature value of the first anisotropy constant was observed.
