    Magnetic and magnetoelastic properties of Fe-Si-B metallic fibers
    (Ieee-Inst Electrical Electronics Engineers Inc, 1996) Atalay, S; Squire, PT; Rudkowski, P
    Amorphous metallic Fe78Si9B13 fibers, 50 mu m in diameter, produced by the melt extraction method, have been studied in the as-quenched state and after furnace annealing at 455 degrees C and 480 degrees C for times between 0.5 min and 50 min. Measurements of the M-H loops and field dependence of Young's modulus have shown that they behave in a way very like that of amorphous wires. The minimum coercivity of 3 A/m is greater than that found in wires, and the minimum Young's modulus (similar to 0.45 times the saturation value) is greater. It is suggested that the core-shell domain model applies in the its-quenched state and that stress relief followed by surface crystallization dominate the anisotropy.
