Abstract
A simple ferromagnetic resonance (FMR) microscope was constructed for analyzing the magnetic properties of thin films of a prototypical colossal magnetoresistance (CMR) manganite, La0.7Sr0.3MnO3. From the 300 K scans, the films show tremendous strains. However, in the best films, the strain is relatively uniform. Unfortunately, on cooling, the FMR spectrum degrades rapidly.
