We report the switching behavior of resistive states induced by current flowing in La_(1-x)Ca_(x)MnO_(3) films. The transport behavior upon treatments by applying a large dc current has been investigated in the absence of magnetic field. A switching from low to high resistive state was found upon applying a large dc current for the both compositions. The critical currents for the switching are 10.5 mA (density of 2.3 X 10~(3) A/cm~(2)) and 6.7 mA (density of 1.6 X 10~(3) A/cm~(2)) for compositions x(velence)0.2 and 0.3, respectively. Our repeated measurements indicate that the high resistive state appeared in the film x(velence)0.2 is much stable. Exposing the sample in air and room temperature does not cause any change of the transport properties. However, for the film with x(velence)0.3, the induced high resistive state behaves with unstable characteristics. Keeping the sample at a low temperature of 20 K, a relaxation to a higher resistive state takes place. The mechanism of phase separation was taken into account in the interpretation of the observed phenomena.
