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

Magnetochemistry, 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

AIP 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.

Spin Diffusion in Double-Exchange Manganites

, 2003
The theoretical study of spin diffusion in double-exchange magnets by means of dynamical mean-field theory is presented. We demonstrate that the spin-diffusion coefficient becomes independent of the Hund's coupling JH in the range of parameters JH*S >> W

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

Materials 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.

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

, 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.

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

New 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 ...

Evolution and control of the phase competition morphology in a manganite film

, 2015
The competition among different phases in perovskite manganites is pronounced since their energies are very close under the interplay of charge, spin, orbital and lattice degrees of freedom.

Magnon scattering processes and low temperature resistivity in CMR manganites

, 2000
Low temperature resistivity of CMR manganites is investigated. At the ground state, conduction electrons are perfectly spin polarized, which is called half-metallic.
