Abstract
A model to describe the low-field microwave absorption of soft magnetic microwires is proposed. The field distributions inside a microwire and microwave absorption are found by means of a solution of Maxwell equations and the Landau–Lifshitz–Gilbert equation. It is shown that the microwave absorption field dependence is sensitive to a domain structure in a microwire surface region. The results obtained are applicable for both the amorphous microwires and the microwires consisting of a conducting nonmagnetic core and a soft magnetic shell.
