    Magnetization and perpendicular magnetic anisotropy have been investigated in the temperature range between 77 and 400 K for evaporated Fe100-xRx (R = Pr, Nd, Sm; 10 {slanted equal to or less-than} x {slanted equal to or less-than} 80) films. The magnetic moment and Curie temperature of these samples were compared with those of amorphous ribbon samples. It seems that there exist no difference between film and ribbon samples in magnetic moment. The iron moment in the amorphous Fe-R alloys decreases with increasing R content. However, the Curie temperature of films is much lower than that of ribbons, especially in x {slanted equal to or greater-than} 30 samples. The dependence of perpendicular magnetic anisotropy on temperature is nearly the same in these amorphous films. The magnetic anisotropy at 77 K exhibits a maximum for Fe-Pr and Fe-Nd films and a minimum for Fe-Sm films at x = 30-40.
