Магнитооптическое исследование доменной структуры и гистерезисных свойств плёночных сред с однонаправленной анизотропией

Abstract

Specific features of magnetization processes taking place in different ferromagnetic layers (Fe10Ni90 and Fe20Ni80) exchange coupled to a Fe50Mn50 antiferromagnetic layer were investigated. It was shown, that the magnetization reversal occurs mostly by changing of the ratio between the volumes of the opposite magnetization phases. It can be interpreted as an indirect evidence of the interface domain wall formation in the antiferromagnetic layer during the magnetization reversal.
