Abstract

Transport properties of Pr1-x Srx MnO3 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 TC. Below TC, 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 La1-x Cax MnO3 manganites.
