| 中文摘要 | Different from the negative colossal magnetoresistance (CMR) of the LaMnO3 compound family, a positive CMR has been discovered at low applied magnetic field and high temperature in the epitaxial p-n heterostructure we fabricated with Sr-doped LaMnO3 and Nb-doped SrTiO3 by laser molecular-beam epitaxy. The mechanism causing the unusual positive CMR is proposed as a interface effect, i.e., the creation of a space charge region at the interface with different electron filling in bands comparing to that in the homogeneous region in Sr-doped LaMnO3. Other puzzling CMR features with bias voltage, temperature, and even composition are well explained by the present scenario. |
