Abstract :
A frequency-and field-swept non-destructive local FMR technique with an external linearly polarized magnetic probe is presented. The main features of this technique are local characterization and mobility: a small area of any location on the magnetic medium can be probed. Samples of arbitrary shape and size can be measured with a spatial resolution and bandwidth that depend only on the probe "tip".Traditionally, ferromagnetic resonance (FMR) measurements are performed in microwave cavities at a fixed frequency and variable applied DC magnetic field.In order to measure ferromagnetic resonance in magnetic materials we have employed an improved near-field microwave probe that provides a high coupling between the sample (external to the probe) and the probe.
