Magnons in Ferromagnetic Metallic Manganites [PDF]

open access: yesChemInform, 2007
Ferromagnetic (FM) manganites, a group of likely half-metallic oxides, are of special interest not only because they are a testing ground of the classical doubleexchange interaction mechanism for the colossal magnetoresistance, but also because they ...

Mechanism of Anomalous Anisotropic Colossal Magnetoresistance in Quasi-2D Mn<sub>3</sub>Si<sub>2</sub>Te<sub>6</sub> Bulk Single Crystal. [PDF]

open access: yesAdv Sci (Weinh)
The external field exceeds Hd, the speed polarization abruptly reorients to align with the Mn magnetic moments, leading to an MR ≈ −100%. Abstract Mn3Si2Te6, quasi‐2D ferrimagnetic semiconductor, exhibits anomalous saturated colossal magnetoresistance (CMR) only when a magnetic field is applied along its magnetic hard magnetization axis, suggesting ...

Influence of Calcium Ions on the Structure and Properties of LaMnO3 [PDF]

open access: yesArchives of Metallurgy and Materials, 2020
La0,7Ca0,3MnO3 polycrystalline were synthesized from La2O3, CaO and MnO2 powder mixture using a solid state reaction technique. The compound powders were obtained through the free sintering method at different temperatures and sintering times in order to

Grain-Size-Induced Collapse of Variable Range Hopping and Promotion of Ferromagnetism in Manganite La0.5Ca0.5MnO3

open access: yesCrystals, 2022
Among transition metal oxides, manganites have attracted significant attention because of colossal magnetoresistance (CMR)—a magnetic field-induced metal–insulator transition close to the Curie temperature. CMR is closely related to the ferromagnetic (FM)

Modelling colossal magnetoresistance manganites [PDF]

open access: yes, 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 ...

Effect of ageing on magnetic and electrical properties of Ti–substituted La-Sr manganites

open access: yesEPJ Web of Conferences, 2018
The changes of structural, magnetic and electrical parameters of ceramic La0.8-xSr0.2+xMn1-xTixO3+γ (0.025 ≤ x ≤ 0.150) manganites during long-term storage at room temperature and after thermal cycling were investigated.
