Abstract
Field annealing experiments on amorphous Fe80B20ribbon (Metglas 2605) and amorphous Fe78Si10B12ribbon (Tsuya, Tohoku University) are reported. The maximum magnetomechanical coupling constant,k, and change in Young's modulus, &E/E0found in Fe80B20were 0.64 and 0.87, respectively, for an anneal of 376& for 6 min in a field of 2.0T. The maximumkfor Fe78Si10B12was found to be 0.82, following a similar anneal at 373&C. This is higher than 0.75 reported by Tsuya and Arai for Fe78Si10B12, previously the highest known for any material.Keywords
