Title
Perpendicular Magnetic Anisotropy of ( Fe , Co ) - Rare Earth Amorphous alloy Films
T . Miyazaki, M . Takahashi
Abstract
Perpendicular magnetic anisotropy has been studied for (M_(100-x)R_x) (M = Fe, Co, R =Pr, Nd, Sm, Gd, Dy, Er) amorphous alloy films. It is found that the perpendicular magnetic anisotropy of amorphous films consists of two terms which are proportional to the content and to the square of content of rare earths. Both of these terms can be explained by a large one ion anisotropy of rare earths.
