Colossal magnetoresistance in an ultra-clean weakly interacting 2D Fermi liquid

, 2010
We report the observation of a new phenomenon of colossal magnetoresistance in a 40 nm wide GaAs quantum well in the presence of an external magnetic field applied parallel to the high-mobility 2D electron layer.

Temperature-dependent pseudogaps in colossal magnetoresistive oxides [PDF]

Physical Review B, 2000
Direct electronic structure measurements of a variety of the colossal magnetoresistive oxides show the presence of a pseudogap at the Fermi energy E_F which drastically suppresses the electron spectral function at E_F. The pseudogap is a strong function of the layer number of the samples (sample dimensionality) and is strongly temperature dependent ...

Features of Modeling of the Magnetorefractive Effect in Multilayered Metal Nanostructures

Российский технологический журнал, 2019
The magnetorefractive effect (MRE) is important and interesting from both fundamental and practical points of view. This effect consists in a change in the reflection coefficient or the passage of an electromagnetic wave from magnetized structures with ...
