Abstract
In the Gd/Fe multilayers, the magnetic moments of the ferromagnetically ordered layers of Gd and Fe lie in the film plane and are oriented antiparallelly due to antiferromagnetic exchange interaction at the interface. It is known that a magnetic field applied in the plane of such film induces the phase transition to the twisted state [1–4]. The collinearity of the magnetic moments of Gd and Fe layers is destroyed at the transition. The spin reorientation to the twisted phase originates from the surface of the Gd/Fe multilayers if the magnetic moment of the outermost layer is opposite to the field direction [3,4]. In the present paper, the other type of the surface spin reorientations induced by a magnetic field has been found in the Gd/Fe multilayers terminated with the Gd layer. A magnetic field induced a noncollinear spin configuration within the outermost Gd layer of multilayer.
