- W2369997488 abstract "Single phase polycrystalline sample La0.7Pb0.3MnO3 is successfully fabricated by conventional solid state reaction.Magnetoreistance effect and transport properties of bulk sample La0.7Pb0.3MnO3 are chiefly studied using superconducting quantum interference device magnetometer and dc four-probe method in this paper.Magnetic properties indicate the transition from ferromagnetic to paramagnetic near the curie point,and exhibit the typical cluster glass characterization.Magnetoresistance reaches a maximum near the curie point,which is a characteristic colossal magnetoresistance effect.The maximum magnetoresistance is 6.8% at 0.5T,and 12.4% at 1T.The transport results show that the sample is a metal because of electron scattering for T1 range,the sample is a semiconductor because of small polar hopping model." @default.
