摘要：
We present magneto-impedance data for a bulk sample of La0.6Y0.1Ca0.3MnO3 manganite for 1.5less than or equal toTless than or equal to300K, for 0less than or equal to Hless than or equal to 6 T, and for the frequency (f) of the electrical current varying from DC to 3 MHz. A broad peak is observed below 0.5 MHz while two-peak spectra are obtained for higher frequencies. (C) 2004 Elsevier B.V. All rights reserved.
