Resumen:
In this article we present d.c. resistivity, a.c. impedance, magnetization and dielectric permittivity measurements in Pr0.67Ca0.33MnO3. A rise in the imaginary part of impedance was detected at the charge ordering transition temperature (T = 225 K). This indicates an intrinsic capacitive behavior of the sample in the charge ordering state. The a.c. impedance is presented here as a valid and easy tool to characterize the charge ordering transition.
