The m-CPWs are connected to a Vector Network Analyzer in order to measure the microwave transmission through the device. For this, m-CPWs are mounted in a brass cavity and placed inside a 1.5 Tesla rotateable electromagnet (for room-temperature experiments) or inside our 3He and 3He-4He dilution cryostats (for low-temperature experiments with our superconducting vector magnet). These magnets allows us to vary the applied field direction with respect to the thin film planes, from the in-plane (0 degrees) to normal to the film plane (90 degrees) configurations.

In the figures on the left there are some FMR absorption curves recorded in a 20nm-thick NiPd ferromagnetic thin film. Anisotropy and magnetostatic effects make the films to behave differently upon application of microwave radiation depending on the direction of the applied magnetic film with respect to the film plane. The figures shows the behavior of the FMR peak as a function of the angle between the fild and the film plane, which corresponds to an in-plane magnetization configuration in this material. The inset shows two FMR absorption curves recorded with the fied in-plane (0 degrees) and out-of-the-plane (90 degrees).
