G. Filoti et al., MAGNETIC-PROPERTIES OF FE100-XGDX THIN-FILMS AND FE80-XGDXB20 THIN-FILMS AND RIBBONS -LESS-THAN-OR-EQUAL-TO-X-LESS-THAN-OR-EQUAL-TO-20), IEEE transactions on magnetics, 29(6), 1993, pp. 3123-3125
Magnetic and Mossbauer experiments were performed on Fe100-xGdx thin f
ilms and on Fe80-xGdxB20 both in thin films and ribbons for x less-tha
n-or-equal-to 20. The ferrimagnetic order is perturbed by the presence
of B and Fe-interactions are.different. For small Gd content, the low
anisotropy is in the film plane, while for greater Gd the anisotropy
goes out of the plane giving typical features of hysteresis loops and
strong decrease of Mossbauer hyperfine fields.
