Inhomogeneous Ferromagnetic Resonance Absorption in Ferrites Detected by Photothermal Techniques
Conference paper
Abstract
Photoacoustic (PA) detection and the photothermal deflection (PD) technique have proved to be valuable tools for magnetic depth profiling and lateral imaging of magnetically inhomogeneous materials [1]. In this work, these techniques have been applied to investigate the lateral and depth dependence of ferromagnetic resonance (FMR) microwave absorption in thin ferrite plates. Although this material possesses homogeneous magnetic and thermal properties, strong inhomogeneities in microwave absorption exist which are due to interfering electromagnetic waves.
