It is reported here that colossal constant magnetoresistance (CCMR) over the whole temperature range below the insulatormetal transition can be realized at low magnetic fields through doping 4% Cu in the sol-gel prepared La 2/3 Ca 1/3 MnO 3 sample sintered at 950 8C. The magnetoresistance defined as
