Abstract

In the present work it has been found that the room temperature impedance of La0.7Sr0.3MnO3 increases with increasing ac frequency from 7.38 to 110 MHz. The room temperature magnetoresistance ratio (R(0)–R(H))⁄R(0) for La0.7Sr0.3MnO3 can reach 31.4% with H=4.92×105 A/m at a frequency of 68.27 MHz. The frequency dependence of magnetoimpedance, as well as magnetoreactance and magnetoresistance, were investigated in detail.
