  • Semi-hard magnetic elements formed by annealing and controlled oxidation of soft magnetic material
    Patent number: 5767770
    Abstract: A semi-hard magnetic element is formed by at least partially crystallizing an amorphous soft iron-metalloid material. The heating process used to achieve crystallization includes a controlled oxidation stage to increase the level of remanent flux that is provided when the processed magnetic element is placed in a fully magnetized state.
