The magnetic spectra of the polycrystalline perovskite La 0.7 Sr 0.3 MnO 3 have been measured at various temperatures and in the frequency range 10 Hz-100 MHz using an impedance analyzer. The complex permeability and the relaxation of magnetic domain walls have been investigated. A pronounced disper
