Abstract

Description

A simplified model is introduced and analysed to show, that for the Landau-Lifshitz equation stable, steady state solutions of domain type exist in ferromagnetic systems, strongly driven by external transverse fields. These dynamic domain states are able to describe the drastic reduction of the power absorption found experimentally above the instability of the homogeneous magnetisation. The excitations of the domain states are presented and the relevance of the model for real ferromagnets is discussed.
