Abstract

Uniform magnetization precession in the ferromagnetic state of La0.67 Sr0.33 Mn O3 films grown on different substrates is investigated in the 50-300 K temperature range in magnetic fields of up to 1.3 T. The precession was induced by an optical pump pulse and probed by a time-delayed pulse using magneto-optical Kerr effect. The measured field dependence of the precession frequency agrees well with calculation from the Landau-Lifshitz-Gilbert equation using different uniaxial anisotropies for different substrates. The field-dependent relaxation times of the exponentially decaying precession are in 100-1400 ps range.
