摘要

We report the magnetic and magnetotransport properties of the polycrystalline manganiteNd0.75Na0.25MnO3. In zero field, the sample shows a ferromagnetic insulator behavior. Under appliedfields higher than 30 kOe, a field-induced insulator-metal, followed by a metal-insulator transition ata lower temperature occur; at the same time the colossal magnetoresistance (CMR) effect is also observed.At the temperature of 5 K, the metamagnetic transition from charge ordering/antiferromagnetic(CO/AFM) to ferromagnetic (FM) state is observed. With increasing temperature, the metastableFMphasecan transform back to the CO state, accompanied by a high field hysteresis. The CMR effect of the samplecan be understood by a percolative regime and is related to the CO-FM transition under a large magneticfield.
