TL;DR: In this article, it was shown that the magnetoresistive response increases dramatically when the Curie temperature (T C) is reduced, and that the massive magnetoresistance in low-T C systems can be explained by percolative transport through the ferromagnetic domains; this depends sensitively on the relative spin orientation of adjacent magnetoric domains which can be controlled by applied magnetic fields.

TL;DR: In this article, a different pattern of charge localization in the charge-ordered phase of the manganese oxide La1−xCaxMnO3 (x ⩾ 0.5) was reported.

TL;DR: In this article, an Epitaxial ferroelectric SrRuO3/Pb(Zr0.52Ti0.48)O3 /SrRuOO3 heterostructures have been fabricated employing isotropic metallic oxide electrodes on (100) SrTiO3 and 100) Si with an yttria stabilized zirconia buffer layer.

TL;DR: A dark-field imaging technique has provided real-space images of charge-ordered domains revealing discommensurations inside the nearly commensurate domains, responsible for the similar variations of the charge-ordering wave vector.

TL;DR: The large-magnetoresistance compounds La, Ca, and MnO have been studied using specific heat, sound velocity, and electron diffraction to imply extremely strong electron-phonon coupling, known to exist for the octahederally coordinated ${d}^{4}$ ion.
