Description
The magnetoresistance effect of bulk samples of La0.67Ca0.33MnO3, prepared by the sol-gel method has been studied under a low applied magnetic field. Quite a large (-37%) negative magnetoresistance ratio (MR) has been obtained at a relatively 'higher' temperature (190 K) with an applied external magnetic field intensity as low as 0.6 T. Observation of the MR peak at a temperature greater than the insulator-metal transition temperature has been made for the first time. (orig.)
