摘要：

Transport properties of Pr1-xSrMnO3 single crystals doped close to the percolation threshold have been investigated. It was found that the resistivity of x = 0.22 crystal obeys the Arrhenius law above T-C. Below T-C, the dynamic resistance starts to depend strongly on bias current and a drop of the activation energy points to a change in the conduction mechanism. The results resemble closely features of the previously investigated La(1-x)CaxMnO(3) manganites. (c) 2005 American Institute Of Physics.
