Strong electron–phonon interaction and colossal magnetoresistance in EuTiO3

open access: yes, 2018
At low temperatures, EuTiO3 system has very large resistivities and exhibits colossal magnetoresistance. Based on a first principle calculation and the dynamical mean-field theory for small polaron we have calculated the transport properties of EuTiO3 ...

Colossal Magnetoresistance in La-Y-Ca-Mn-O Films [PDF]

open access: yes, 1996
Magnetoresistance behavior of La0.60Y0.07CaMnOx, thin films epitaxially grown on LaAlO3 has been investigated. The films exhibit colossal magnetoresistance with the MR ratio in excess of 10^8% at ~60K, H = 7T, which is the highest ever reported for thin ...

Elementary Steps of Energy Conversion in Strongly Correlated Systems: Beyond Single Quasiparticles and Rigid Bands

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
This article reviews the fundamental consequences of strong correlations on excitations and elementary steps of energy conversion leading to new opportunities to control energy conversion. Examples include friction at surfaces, thermal transport, and photovoltaic energy conversion.

Percolation and the Colossal Magnetoresistance of Eu-Based Hexaboride [PDF]

open access: yesPhysical Review Letters, 2004
Upon substituting Ca for Eu in the local-moment ferromagnet EuB6, the Curie temperature T(C) decreases substantially with increasing dilution of the magnetic sublattice and is completely suppressed for ...

Colossal enhancement of magnetoresistance in La

open access: yes, 2008
Colossal enhancement of magnetoresistance has been achieved over a broad temperature range which extends up to the room temperature, in ferromagnetic metal-charge$\hbox{--} $ordered insulator manganite multilayers.

Machine Learning‐Assisted Second‐Order Perturbation Theory for Chemical Potential Correction Toward Hubbard U Determination

open access: yesAdvanced Intelligent Discovery, Volume 2, Issue 5, October 2026.
In this work, the Doubao large language model (LLM) is involved in the formula derivation processes for Hubbard U determination regarding the second‐order perturbations of the chemical potential. The core ML tool is optimized for physical domain knowledge, which is not limited to parameter prediction but rather serves as an interactive physical theory ...

Insulator/metal phase transition and colossal magnetoresistance in holographic model [PDF]

open access: yes, 2015
Within massive gravity, we construct a gravity dual for insulator/metal phase transition and colossal magnetoresistance (CMR) effect found in some manganese oxides materials.

Absence of colossal magnetoresistance in the oxypnictide PrMnAsO0.95F0.05. [PDF]

open access: yesInorganic Chemistry, 2015
We have recently reported a new mechanism of colossal magnetoresistance (CMR) in electron doped manganese oxypnictides NdMnAsO1-xFx. Magnetoresistances of up to -95% at 3 K have been observed.
