Abstract
An Fe-based amorphous/nanocrystalline bilayer ribbon was prepared by rapid quenching and subsequent annealing. The B-H loop exhibited a high permeability at low field and a slow approach to saturation, quite unlike the two-step B-H loop of lap-wound individual amorphous and nanocrystalline monolayer ribbons. This result for bilayered ribbon indicates the occurrence of magnetomechanical interaction due to interlayer stresses induced on annealing to the point of nanocrystallization.
