Abstract
We report on the study of high-frequency magneto-transport properties in th e sintered La1-xCaxMnO3 oxides. Experimental results have demonstrated a gi ant magneto-impedance (GMI) effect, much larger than the DC magnetoresistiv e effect, in these manganese oxides. The temperature and frequency dependen ce of the magneto-impedance is dependent on the ratio of Mn+3/Mn+4 and the magnetic phase state in these compounds. Our result implies a possible sens itive probe of complex phase states at high frequency and the further techn ical GMI applications. 2000 Elsevier Science B.V. (C) All rights reserved.
