Abstract
Exchange-spring TbFe/CoYFeCo multilayers exhibit interesting magnetic and magnetostrictive propertiesthat are rather promising for applicationin microsystems. In this paper, we present a study of the effect of the exchange coupling on the magnetic properties of these magnetostrictive multilayers. An exchangebias phenomenon,revealed by a shift of the minor hysteresis loop along the applied field axis, is found as the result of the creation of interfacial domain walls. This effect strongly depends on the magnetic properties of the soft YFeCo layer, and becomes more pronounced at low temperatures due to the enhancement of the magnitude of the exchange coupling between the layers.
