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

## Abstract In this work, the permeability spectra of La~0.7~Sr~0.3~MnO~3~ perovskite with mean grain size (__D__) ranging from 1200 to 45 nm have been investigated at 293 K. The spectra exhibit a typical relaxation, relating to reversible domain wall motions. The quasi‐static permeability (__ΞΌ~e~_
