Abstract :
Field annealing experiments on amorphous Fe80 B20 ribbon (Metglas 2605) and amorphous Fe78 Si10 B12 ribbon (Tsuya, Tohoku University) are reported. The maximum magnetomechanical coupling constant, 
, and change in Young\´s modulus, ΔE/E0 found in Fe80 B20 were 0.64 and 0.87, respectively, for an anneal of 376° for 6 min in a field of 2.0T. The maximum for Fe78 Si10 B12 was found to be 0.82, following a similar anneal at 373°C. This is higher than 0.75 reported by Tsuya and Arai for Fe78 Si10 B12 , previously the highest known for any material.
