Abstract

The effect of heat treatment and partial oxidation of an Fe50Mn50 layer on the structure and magnetic properties of exchange-coupled Fe20Ni80/Fe50Mn50 layers has been investigated. The behavior of the exchange-bias field and coercive force depending on the temperature of annealing upon heat treatment in a vacuum or in an oxygen-containing gas mixture has been studied. It has been shown that, by adjusting the parameters of annealing in the gas mixture, it is possible to increase the field of switching of the exchange-coupled Fe20Ni80/Fe50Mn50 layers.
