Reversible permeability for perpendicularly superposed induction for Fe₄₀Ni₄₀P₁₄B₆amorphous ribbon and its magnetisation process

Abstract

Measurements of the reversible permeability for perpendicularly superposed induction have been made in tape-wound cores of Fe40Ni40P14B6 amorphous ribbons. The results obtained show an increase of the permeability followed by a decrease, that reveals important magnetisation rotation processes in these materials.
