Abstract

The surface scanning ferromagnetic resonance (FMR) was analyzed using inductive microwave detection and thermal detection. The patterned layers of dispersed magnetite Fe₃O₄ nanoparticles were used to demonstrate low-field FMR images with spatial resolution of 15 μm. The localized heating of magnetite nanoparticles via FMR absorption was also demonstrated which was controlled by an external dc magnetic field. The results show that sensitivity in inductive microwave detection at low power was limited by presence of paramagnetic impurities in material of probe.
