PhD topic: Chaotic states in nanoscale spintronic oscillators

Scientific project

Ferromagnets are ordered spin systems in which a variety of nonlinear phenomena are possible. An interesting example in thin films is the magnetic vortex, which comprises a topological spin structure in which moments circulate in the plane of the film but culminate in a perpendicular direction at the vortex core – a compact region 10-20 nm in size. When an electrical current is applied to the vortex the flow of electron spins exert a torque on the magnetic moments, which leads to novel dynamics like steady state gyration of the vortex core that is inherently non-Newtonian [1].
