摘要
The low-temperature minimum of the La0.85Ag0.15 MnO3 resistivity has been investigated. The analysis of the experimental data shows that this minimum of resistivity in zero magnetic field and the large magnetoresistive effect, which increases with a decrease in temperature, can be explained within the model of spin-polarized tunneling of carriers through grain boundaries. © Allerton Press, Inc. 2009.
