Abstract
A wide range of hydrogenated amorphous rare earth-transition metal (R-T) alloys has been synthesized using a newly developed vapor deposition synthesis procedure. Measured H/R ratios vary from 2 to 5 depending on composition. The R-T films do not fracture or disintegrate when activated as do crystalline alloys. Magnetic and electrical results are given for the a-Gd xFe 1−x system. The inclusion of hydrogen sharply reduces the compensation temperature by 200K and the Curie temperature by 50K at a given composition. The dominant magnetic effect is a reduction of the GdFe exchange interaction. Potential application advantages of hydrogenated amorphous R-T alloys are also discussed.
