Thousandfold Change in Resistivity in Magnetoresistive La-Ca-Mn-O Films
TL;DR: A negative isotropic magnetoresistance effect has been observed in thin oxide films of perovskite-like La0.67Ca0.33MnOx, which could be useful for various magnetic and electric device applications if the observed effects of material processing are optimized.

Low temperature magnetoresistance and the magnetic phase diagram of La1-xCaxMnO3.
TL;DR: An unexpectedly large magnetoresistance is seen at low temperatures in the FM phase, and is largely attributed to unusual domain wall scattering.

Large Low-Field Magnetoresistance in La0.7Ca0.3Mno3 Induced by Artificial Grain-Boundaries
Neil D. Mathur,Gavin Burnell,S. P. Isaac,Timothy J. Jackson,B.-S. Teo,Judith L. MacManus-Driscoll,Lesley F. Cohen,J.E. Evetts,Mark G. Blamire +8 more
TL;DR: In this article, the effect of specific structural defects on the CMR behavior of the compound La0.7Ca0.3MnO3 was elucidated, and thin film devices were made to isolate the contribution of a single grain boundary that was introduced into an epitaxial film of the material.
Journal ArticleDOI
Electronic structure of CMR manganites (invited)
TL;DR: In this paper, the authors show that negative magnetoresistance (CMR) occurs in manganites at a first-order ferromagnetic transition and that the CMR is greatest near t≈0.98 where the transition at TC is first order.
