Polycrystalline perovskite Pr_0.7Ca_0.3CoO₃ and Pr_0.5Ca_0.5CoO₃ have been investigated by electrical resistivity, magnetization, ac susceptibility, and μSR measurements. The magnetic measurements data indicate that the samples have, at low temperatures, similar properties to the frustrated magnets. The μSR measurements, suggest the presence of magnetic clusters at low temperatures. The electrical behavior has the main features of conduction in a phase separated system: it shows negative magnetoresistance and it is controlled by grain-boundary effects.
