摘要：
The magnetic and electrical transport properties of the colossal magnetoresistance material La2/3Ca1/3MnO3 were studied. It is found that the insulator-metal transition is well consistent with the paramagnetic-ferromagnetic transition,and shifts to higher temperature with increasing applied magnetic field. These results suggest that the transport properties are triggered by the magnetic structure transition and consequently result in a CMR near T C.
