Abstract

Ceramic Pr1 xCaxMnO3 (x = 0.1) samples were prepared by solid-state reaction and the electrical and magnetic transport properties were studied by direct current (DC) and alternating current (AC) methods in different fields. A Curie temperature of 125 K determined by I-V measurements of ceramic Pr1 xCaxMnO3 (x = 0.1) samples is consistent with that from vibrating - sample magnetometer (VSM) measurements. Fitting by Arrhenius law, the barrier height of grain boundary is 145 meV which is well coincident with that from fitting the R-T data. The Cole-Cole semicircles and temperature spectrum of impedance in different electrical and magnetic fields show that there is neither notable ER and MR effects above the Curie temperature of Pr0.9Ca0.1MnO3.
