Effects of heat treatment in air on soft magnetic properties of FeCoSiBPC amorphous core

Correlation of Magnetomechanical Coupling and Damping in Fe80Si9B11 Metallic Glass Ribbons

“…This α relaxation further enhanced the diffusion of the atoms, affecting the atomic orderings in a larger scale and usually reshaping the clusters. Fe or metalloid atoms experiencing long-term relaxation in the B-rich area led to the generation of some clusters with high elasticity, which increased the values of E. In addition, because the annealing procedure in this article was performed in air, the oxidation was stronger and penetrated deeper into the ribbons at a high T AN ; this also had a strong influence on the rigidity of the ribbon [4,20].…”

“…Over recent decades, the influence of annealing on magnetic properties of Fe-based amorphous ribbons has been vastly studied [4,[16][17][18]. It has been found that the annealing procedure can adjust the saturation magnetic flux density (B s ), coercivity (H c ), magnetic permeability (µ r ) and the k, Q and η factors, but variations to these parameters are rarely independent [1,4,8,[11][12][13][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. Thus, an opportunity has arisen for researchers to explore ways to cooperatively elevate two or more parameters while avoiding negatively impacting others [1][2][3].…”
