Singlephase polycrystalline samples of La067Pb033MnO3 were prepared by conventional solidstate reaction method. The crystal structure and magnetic and transport properties are investigated. The structure revealed by the room temperature xray powder diffraction is rhombohedral(R3C), and the Curie temperature is very close to TMI(=360K). At the Curie point, the magnetic properties show the transition from ferromagnetic to paramagnetic, and the conductivity changes from metal to semiconducting. The resistivity decreases with increasing magnetic field. Magnetoresistance reaches a maximum at the Curie point. The maximum magnetoresistance is 14\^5% at H=1\^2MA/m, and 9% at H=0\^6MA/m. The transport results show that the transport data satisfy ρ(T)=ρ0+ρT2.5 for TTMI. This phenomenon is due to the magoncarrier scattering.
