  In this study we report the structure, magnetic and electrical transport
properties of pervoskite oxide La$sub{0.9}Tesub{0.1}MnOsub{3}$. This is a novel
material with the space group R-3c, which shows the spin-glass-like feature at
low temperature and has a good colossal magnetoresistance behavior. The
magnetoresistance ratio is about 51% at 200 K in a field of 4 T. The XPS
measurement suggests that Te ions are in the Te$up{4+}$ state, while Mn ions
may be in the 2+ and 3+ valence state.
