Modelling colossal magnetoresistance manganites [PDF]
Journal of Physics: Condensed Matter, 2007 I briefly survey here attempts to model the rich and strange behaviour of colossal magnetoresistance manganites, after outlining some of the phenomena observed in them, and describing the three relevant strong local interactions of the e_g electrons (in two different orbital states at each site), namely with Jahn-Teller phonon modes (strength g), with ...

Colossal magnetoresistance in manganites and related prototype devices [PDF]
Chinese Physics B, 2013 We review colossal magnetoresistance in single phase manganites, as related to the field sensitive spin charge interactions and phase separation; the rectifying property and negative/positive magnetoresistance in manganite/Nb:SrTiO3 pn junctions in relation to the special interface electronic structure; magnetoelectric coupling in manganite ...

Rapid synthesis of colossal magnetoresistance manganites by microwave dielectric heating
, 2000 Colossal magnetoresistance manganites have been synthesised by the microwave dielectric heating of metal nitrates, which act both as effective microwave susceptors, and a ready source of oxidizing NO2 to induce mixed ...

Field‐Frustrated Cooperative Distortions: Suppressing Jahn‐Teller Ordering via Microwave Annealing
Advanced Science, Volume 13, Issue 48, 28 August 2026.Microwave annealing decouples local Jahn‐Teller distortions from long‐range cooperative ordering in CuFe2O4, stabilizing a metastable cubic phase that remains locally distorted yet globally symmetry‐frustrated. Synchrotron XRD, PDF, XPS, and in situ thermal cycling reveal how non‐equilibrium MW‐phonon interactions suppress cooperative orbital‐lattice ...

Isotope effects in colossal magnetoresistance (CMR) manganites
, 2018 Oxygen isotope effects observed in the metallic and the charge ordered phase of colossal magnetoresistance manganites are investigated by employing the combined theoretical model of the double exchange and interacting lattice polaron mechanism.

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics
Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

Giant magnetoimpedance and colossal ac magnetoresistance of a Cu coil wound on La0.67Sr0.33MnO3
, 2011 We observed the giant magnetoimpedance and colossal ac magnetoresistance for a Cu coil wound on La0.67Sr0.33MnO3 under low dc magnetic fields. Even though the dc magnetoresistance ΔRR0 for La0.67Sr0.33MnO3 plate is only -2.4% under H=12 kOe, a Cu coil ...

Magnetic Polaronic Exciton in A‐Type 2D van der Waals Bulk Material CrSBr
Aggregate, Volume 7, Issue 6, June 2026.Schematic of the excitonic landscape in CrSBr. Multiple excitonic channels emerge below the charge‐transfer band edge (∼500 nm): isolated Cr3+ d–d excitons (PL1 ∼720 nm), magnetically activated dark excitons (PL1a ∼850 nm), ferromagnetically coupled excitons (PL2 ∼920 nm, maximum near 140 K), and interlayer excitons (PL3 ∼990 nm, vanishing above the ...
