Magnetic Anisotropy in La_0.8Sr_0.2MnO_3: Electron Spin Resonance

J. Deisenhofer, H. -A. Krug von Nidda, A. Loidl +4

We report on Ferromagnetic-Resonance experiments in a single crystal of La_0.8Sr_0.2MnO_3 in the temperature range from 4 to 300 K. The observed anisotropy of the resonance line ch…
