Spin valve device and method for forming a spin valve device

摘要: The present disclosure proposes a spin valve device comprising a layer stack. The layer stack comprises one or more layers forming a unidirectionally magnetized reference system, a vortex-magnetized free layer, a non-magnetic layer separating the reference system from the free layer, and one or more layers forming a bias structure being exchange-coupled to the free layer, the bias structure having a vortex-magnetization with closed flux of a predetermined rotation direction.
