Colossal electroresistance without colossal magnetoresistance in La0.9Sr0.1MnO3 [PDF]

Applied Physics Letters, 2007
The authors report on colossal electroresistance (ER) in the ferromagnetic insulator manganite La0.9Sr0.1MnO3. The single crystal samples exhibit a transition into a low resistive state above a certain threshold current. Pulsed measurements demonstrate that this transition is not a consequence of heating.

Spin colossal magnetoresistance in an antiferromagnetic insulator [PDF]

Nature Materials, 2018
Colossal magnetoresistance (CMR) refers to a large change in electrical conductivity induced by a magnetic field in the vicinity of a metal-insulator transition and has inspired extensive studies for decades\cite{Ramirez1997, Tokura2006}. Here we demonstrate an analogous spin effect near the Néel temperature $T_{\rm{N}}$=296 K of the antiferromagnetic ...

Impact of NiO nano-particles on colossal magneto-resistance of La0.70Ca0.30MnO3 composite

Materials Letters: X, 2022
Mixed-valent perovskite manganite has gained considerable research interest due to the increasing demand for energy storage materials. Herein, we show that colossal magneto-resistance properties of La0.7Ca0.3MnO3 (LCMO) can be changed via nickel oxide ...

Chemical ordering suppresses large-scale electronic phase separation in doped manganites

Nature Communications, 2016
In oxide materials, cation doping strongly influences the electronic correlations which promote diverse phenomena such as colossal magnetoresistance and superconductivity.

COLOSSAL MAGNETORESISTANCE BOLOMETER

Acta Physica Sinica, 2000
Based on the sharp resistance change near the metal-insulator transition (M-I) of the colossal magnetoresistance (CMR) materials, we design and test a new type CMR bolometer. La0.67Ca0.33MnO3 epitaxial thin films were used as the photosensitive element of the bolometer, and the optical response of this device to the He-Ne laser and the blackbody were ...
