摘要：
In the present work, the giant magnetoimpedance effect has been found in La0.65Sr0.35MnO3. The impedance, resistance and reactance of La0.65Sr0.35MnO3 depend sensitively on the ac current frequency and dc magnetic field. The magnetoimpedance ratio (Z(0)- Z(0.8 kOe))/Z(0) increases from 0.47% to 2.40% with increasing ac frequency from 0.5 to 12 MHz. (C) 2001 Elsevier Science B.V. All rights reserved.
