G. Suran et al., MAGNETIC-ANISOTROPY INDUCED BY FIELD APPLIED DURING DEPOSITION IN SPUTTERED AMORPHOUS COZR-RARE EARTH THIN-FILMS, IEEE transactions on magnetics, 29(6), 1993, pp. 3055-3057
The formation of the coherent magnetic anisotropy was investigated in
amorphous (Co0.93 Zr 0.07)100-x (RE)x RE = rare earth films as a funct
ion of the magnitude of the magnetic field H(d) applied during deposit
ion. The direction of the induced anisotropy depend upon the peculiar
rare earth substituted. For RE = Sm and Gd a biaxial anisotropy is for
med composed of a perpendicular anisotropy K(p) and of K(u). The devel
opment of K(p) is linked to H(d) . K(p) is negligible for very small H
(d) and increases strongly, and the short range chemical inhomogeneiti
es are progressively suppressed as H(d) is increased. A mechanism is s
uggested to explain the results.
