Showing papers on "Colossal magnetoresistance published in 1981"
TL;DR: This paper measured the temperature and magnetic field dependence of the resistivity of palladium films of ∼ 25 A thickness and found a logarithmic temperature increase with decreasing temperature and a large, positive, isotropic, temperature dependent magnetoresistance.
Abstract: We have measured the temperature and magnetic field dependence of the resistivity of palladium films of ∼ 25 A thickness. We find a logarithmic temperature increase with decreasing temperature and a large, positive, isotropic, temperature dependent magnetoresistance. Similar results with PdAu films show that the effect is not magnetic in origin. The temperature coefficient and positive magnetoresistance are consistent with an interpretation in terms of the interaction picture rather than localization effects.

TL;DR: In this article, the authors report on magnetoresistance measurements in longitudinal and transverse magnetic fields up to 320 kG for silver and gold containing rare-earth impurities and derive the magnitude of the electron-quadrupole interaction from the analysis of the results.

TL;DR: In this paper, a brief outline is given of some of the more important magnetoresistance effects seen in the IV-VI semiconductors and the use of weak-field magnetoreduction to examine strain in thin film samples is presented in more detail.
Abstract: A brief outline is given of some of the more important magnetoresistance effects seen in the IV-VI semiconductors. In addition, an interesting strong magnetic field magnetoresistance phenomenon is exhibited and the use of weak-field magnetoresistance to examine strain in thin film samples is presented in more detail. Data showing the effects discussed are given using PbTe thin films as examples.
