Abstract :
The temperature dependence of resistivity and EPR line intensity of Pr0.7Ba0.3MnO3 manganites was explained in the frame of the polaron hopping model. The difference in activation energy deduced from the dependence can be caused by the decrease of the energy in magnetic field, where the EPR resonance was observed.
