Determination of Layer Specific Magnetization and Anisotropy Fields in Multilayer Garnet Films from FMR and VSM Measurements

A new method is developed to measure the magnetizations in each layer of a multi-layered garnet film. This method combines a single VSM and multiple FMR measurements to completely characterize the magnetic properties of layers. This method can be immediately extended to the case of multiple layers or different materials, as long as the requirement for resolving the FMR absorption peaks for different layers is satisfied.
