Lattice dynamics in colossal magnetoresistance manganites

, 2019
Based on the Hamiltonian of small polarons with strong electron-phonon interaction, we have investigated anomalous behaviors of the sound velocity in colossal magnetoresistance (CMR) manganese oxides. In the low-doping metallic regime, the sound velocity

Metal-insulator transition in colossal magnetoresistance materials

, 2000
We report on resistivity measurements in La0.67Ca0.33MnO3 and Nd0.7Sr0.3MnO3 thin films in order to elucidate the underlying mechanism for the colossal magnetoresistance behavior. The experimental results are analyzed in terms of quantum phase-transition

Kronig-Penney-Ising picture of colossal magnetoresistance

, 1999
peer reviewedFrom general arguments, it is shown that a magnetic Kronig-Penney model based on the thermodynamics of an Ising model can be used for describing the colossal magnetoresistance (CMR) phenomenon.

Colossal Magnetoresistance in Twisted Intertwined Graphene Spirals [PDF]

, 2023
Colossal magnetoresistance (CMR) is highly applicable in spintronic devices such as magnetic sensors, magnetic memory, and hard drives. Typically, CMR is found in Weyl semimetals characterized by perfect electron-hole symmetry or exceptionally high ...

Positive and negative colossal magnetoresistance in a spin glass selenide spinel

, 2004
We present a new class of colossal magnetoresistance materials based on a series of frustrated spinels. The spin glass-like compound Zn0.95Cu0.05Cr2Se4, shows a field-induced transition to a ferromagnetic, which is associated with a highly unusual ...
