Determining the equilibrium magnetic state of superconducting/ferromagnet heterostructures using polarised neutron reflectometry

Abstract: Spin triplet Cooper pairs are a key ingredient to realising superconducting spintronic devices as they provide both a source of supercurrent and carry a net spin. The observation of long-range triplet supercurrents in superconductor/ferromagnet bilayers, where the ferromagnet displays some non-collinear magnetism, has generated substantial interest in such heterostructures as a means to both generate and manipulate non-dissipative spin correlations and build spin-based devices.In order to understand how to control long-range triplets devices, we must also understand the equilibrium magnetic configuration in ferromagnet/superconductor layers. In this proposal we will aim to determine the equilibrium configuration of a multilayer device and combine this understanding with time resolved magnetisation dynamics measurements to probe the interplay between triplet currents and magnetic state.
