The colossal magnetoresistance (CMR) effect and the low-field magnetoresistance (LFMR) of the electron-doped manganites La1-xTexMnO3 (x=0 04, 01) 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: app earing-disappearing-appearing again. Furthermore, the samples exhibited large CM R in the temperature regime where the LFMR disappear. These related results have been analyzed.
