Paper Abstract

In order to gain a more reliable description of the magnetic state in the exchange-coupled films, experiments on the Hall effect in multilayer structures and computer simulations of the observed Hall effect behavior, using the distributed domain wall model, were performed. It was demonstrated that this approach can give insight into the effect of exchange interaction on the magnetization directions in TbDyFeCo/TbFeCo exchange-coupled double layer films with various extra intermediate layer.
