Influence of Annealing Temperature on Magnetic Properties in Co-Based Amorphous Ribbons

Article Preview

Abstract:

The magnetic properties were investigated on Co66Fe4B15Si15 amorphous ribbons of annealed at temperature range from 473 K to 773 K in vacuum (A-batch) and open air (B-batch). Static permeability from domain wall motion decreases with annealing temperature both in A- and B-batch sample. The permeability from magnetization rotation increases up to 700 K annealing temperature, but then decreases. The GMI profiles show a symmetric curve in A-batch samples irrespective of annealing temperature. In B-batch samples, symmetric profiles are shown up to 650 K annealing temperature, while they becomes asymmetric for further annealing temperature, due to the exchange bias-field induced by surface crystalline layer.
