Abstract :
Measurements have been made of the ΔE effect for ribbon specimens of METGLAS 2605SC annealed in fields at angles between 60° and 90° to the long axis. The magnetoelastic behavior of obliquely annealed amorphous ribbons demonstrates features that cannot be explained by the original Livingston model of simple moment rotation. An extension of the Livingston model has been developed and is used to obtain theoretical curves that reproduce the main features of the results. It has been found necessary to include a distribution of initial moment angles, as proposed by M. Melamud et al. (1987), and also a distribution of anisotropy fields
