Effect of Magnetic Annealing on the Properties of (110) [001] Oriented 3 14% Silicon-Iron Strip

摘要

Polycrystalline 3 14% silicon-iron strip with (110) [001] texture was heat-treated in a magnetic field. Both ac and dc properties were investigated before and after magnetic annealing with the field parallel to the , , and directions. Distinct improvement in properties was obtained, particularly in the and directions. This improvement is the result of the realignment of domain boundaries to directions that more nearly coincide with the direction of the applied field. The anisotropy energy that arises from the magnetic annealing is about 900 ergs/cm3, which is but a small fraction of the magnetocrystalline anisotropy energy of this material.
