Abstract

Amorphous Terfenol-D(Tb0.3Dy0.7Fe2) film with high magnetization in weak fields is essential to weak magnetic sensors. The influences of a constant 100 Oe magnetic field parallel to the film plane during the deposition are studied. Then the film was annealed at different temperatures to discuss the effects of annealing on the magnetization of Terfenol-D film. The magnetization of Terfenol-D film could be enhanced by incremental saturation magnetization and decreased effective anisotropy constant. The magnetization at 100 Oe of 0.47 eμg was obtained with the annealing at 600°C for 10 minutes.
