%X The colossal magnetoresistance (CMR) effect and the low-field magnetoresistance (LFMR) of the electron-doped manganites La 1 -x Te x MnO 3 ( x =0.04, 0.1) have been observed. The experimental results showed that LFMR of the samples varied with the increase of temperature from 5 to 300 K as follows: appearing-disappearing-appearing again. Furthermore,the samples exhibited large CMR in the temperature regime where the LFMR disappear. These related results have been analyzed.
