Low-field magnetoresistive properties of polycrystalline and epitaxial perovskite manganite films
TL;DR: The low-field magnetoresistance properties of polycrystalline La0.67Sr0.33MnO3 and La 0.67CaO33MnsO3 thin films with different grain sizes have been investigated and compared with epitaxial films as discussed by the authors.

TL;DR: In this paper, a trilayer epitaxial thin film device based on the doped perovskite manganates La-Ca-Mn-O and La-Sr-mn−O was constructed and large resistance changes, up to a factor of 2, can be induced by a moderate applied magnetic field below 200 Oe in these trilayers supporting current-perpendicular-to-plane transport.

Colossal magnetoresistance of 1 000 000‐fold magnitude achieved in the antiferromagnetic phase of La1−xCaxMnO3
TL;DR: The record values of colossal magnetoresistance (CMR) have been achieved in the antiferromagnetic phase of the La1−xCaxMnO3 system.
