Abstract

This article describes a novel approach which allows for the mutual determination of a ferromagnetic thin film's static and dynamic magnetic behaviours in the presence of an external thermodynamic stimulus. Using a combination of polarized neutron reflectometry (PNR) and ferromagnetic resonance (FMR) techniques, it is shown that information such as magnetic depth profiles and magnetization dynamics can be obtained for a ferromagnetic film in both transient and static states in the presence of a hydrogen gas atmosphere. Presented here are the proposed scheme, the instrumentation concept and the first experimental results obtained fro m implementing a custom-made PNR with an in situ FMR sample chamber on the PLATYPUS time-of-flight reflectometer beamline at the Australian Centre for Neutron Scattering (ANSTO)
