Hidden Charge‐Order in the Mixed‐Valent K0.75Li2Cr6O12 High‐Pressure Oxide

open access: yesAdvanced Science, Volume 13, Issue 11, 23 February 2026.
K0.75Li2Cr6O12 is one of the few mixed valent chromium oxides. It shows a single angle spiral magnetic structure with a k = [1/3 1/3 ¼] propagation vector. Density functional theory reveals a hidden charge order that is necessary to stabilize the antiferromagnetic (AFM) ground state.

Electric-pulse-induced resistance switching effect in the bulk of La0.5Ca0.5MnO3 ceramics

open access: yesAIP Advances, 2014
In the majority of contributions, the electrical–pulse-induced resistance (EPIR) switching effect of perovskite manganites is thought to originate from the extrinsic interfacial Schottky barrier between the metal electrode and the surface of sample.

Critical Behavior of La0.8Ca0.2Mn1−xCoxO3 Perovskite (0.1 ≤ x ≤ 0.3)

open access: yesMagnetochemistry, 2017
The critical properties of La0.8Ca0.2Mn1−xCoxO3 (x = 0, 0.1, 0.2 and 0.3) compounds were investigated by analysis of the magnetic measurements in the vicinity of their critical temperature. Arrott plots revealed that the paramagnetic PM-ferromagnetic (FM)

Controllable magnetization and resistivity jumps of manganite thin films on BaTiO3 substrate

open access: yesAIP Advances, 2015
Manganites thin films grown on ferroelectric BaTiO3 (BTO) exhibit dramatic jumps for both magnetization and resistivity upon cooling in accordance with the temperature-dependent structural transitions of the BTO substrate.

Enhancement of temperature coefficient of resistance (TCR) and magnetoresistance (MR) of La0.67–xRExCa0.33MnO3 (x = 0, 0.1; RE = Gd, Nd, Sm) system via rare-earth substitution

open access: yesMaterials Research Express, 2020
We investigated the influence of 10% substitution of rare-earth (RE) elements on the crystallographic, transport, and magnetic properties of La _0.67– _x RE _x Ca _0.33 MnO _3 (RE = Nd, Sm, and Gd, x  = 0.0, 0.1) manganite perovskite compounds.

Efectos intergranulares en perovskitas de manganeso nanocristalinas

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2000
Intergranular magnetotransport effects are studied on polycrystalline manganites. Reducing grain size through sol-gel technology allows us to show new results on these materials.

Giant dielectric permittivity and magneto-capacitance effects in low doped manganites

open access: yesNew Journal of Physics, 2014
The effect of giant dielectric permittivity due to phase separation accompanied by charged inhomogeneities in low-doped manganites is discussed. The effect appears in the vicinity of the second-order magnetic phase transition and is caused by long-range ...

Chemical and thermomechanical compatibility between neodymium manganites and electrolytes based on ceria

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2008
The goal of this work was to study the thermal expansion behaviour and to establish the phase relations between NdMe0.5Mn0.5O3 (Me=Ni, Co) solid solutions as cathodes and two electrolytes based on Ce0.9Gd0.1O1.95. Doping of electrolyte with 1.0 wt% Bi2O3

Novel stripe-type charge ordering in the metallic A-type antiferromagnet Pr{0.5}Sr{0.5}MnO{3}

open access: yes, 2001
We demonstrate that an A-type antiferromagnetic (AFM) state of Pr{0.5}Sr{0.5}MnO{3} exhibits a novel charge ordering which governs the transport property.

Nanosized Sodium-Doped Lanthanum Manganites: Role of the Synthetic Route on their Physical Properties

open access: yes, 2003
In this paper we present the results of the synthesis and characterisation of nanocrystalline La1-xNaxMnO3+delta samples. Two synthetic routes were employed: polyacrylamide-based sol-gel and propellant synthesis.
