Structure, Magnetic Properties and Spin-glass Behavior in La
arXiv:cond-mat/0301384 · doi:10.1063/1.1578696
Abstract
In this study we report the structure, magnetic and electrical transport properties of pervoskite oxide La. 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 state, while Mn ions may be in the 2+ and 3+ valence state.
