Abstract
Prepared rare-earth La modified amorphous ribbon by doping Rare-earth La in Fe78Si9B13 amorphous alloy. Investigated rare-earth content and temperature, as well as their influence on the magnetic induction effect and it’s amplitude. The results show that, when magnetic field is less than 1356 A / m, with the increase of Rare-earth content ,the magnetic induction effect first increased and then decreased, when the magnetic field strength greater than 1356 A / m, the Rare-earth content influence little on magnetic induction effect , changing amplitude of magnetic induction effect shows first increased and then decreased with increasing Rare-earth content; temperature influence little on the magnitude of magnetic induction effect.
