摘要：
The current-voltage characteristics and magnetotransport properties of La0.7Sr0.3MnO3/Nb(1.0%) : SrTiO3 junctions under various currents ranging from 10(-6) to 10(-3) A and different temperatures ranging from 10 to 300 K were investigated. The current-voltage curves exhibit rectifying behavior. The resistance, magnetoresistance, and electroresistance of the junctions are strongly dependent on bias-current direction, current, temperature, and magnetic field. A detailed analysis of the conductance-voltage curves showed that quantum mechanical tunneling was the dominating transport mechanism. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3068421]
