Abstract
We report on Ferromagnetic-Resonance experiments in a single crystal of La0.8Sr0.2MnO3 in the temperature range from 4 to 300 K. The observed anisotropy of the resonance line changes on crossing the transition from the orthorhombic O-phase to the rhombohedral R-phase at T~100 K and indicates a reorientation of the spins at about 130 K.
