Magnetic and electron paramagnetic resonance studies of Ln0.5Ca0.5MnO3 (Ln = Pr, Bi) manganite

open access: yesAIP Advances, 2021
In this paper we compare the magnetic and electron paramagnetic resonance (EPR) properties of Pr0.5Ca0.5MnO3 (PCMO) and Bi0.5Ca0.5MnO3 (BCMO) charge ordered manganites. PCMO and BCMO samples were prepared by solid state reaction method.

Solitonic Phase in Manganites [PDF]

open access: yesPhysical Review Letters, 2005
Whenever a symmetry in the ground state of a system is broken, topological defects will exist. These defects are essential for understanding phase transitions in low dimensional systems[1]. Excitingly in some unique condensed matter systems the defects are also the low energy electric charge excitations.

Structural, Magnetic, and Electrical Properties and Magnetoresistance of Monovalent K-Substituted La0.7Ba0.3−xKxMnO3 (x = 0 and 0.04) Manganite

open access: yesCondensed Matter, 2022
The effects of K+ substitution at the Ba-site on the structural, magnetic, and electrical properties and magnetoresistance (MR) of La0.7Ba0.3−xKxMnO3 (x = 0 and 0.04) manganites prepared via the solid-state method were investigated.

Theory of manganite superlattices [PDF]

open access: yesPhysical Review B, 2008
A theoretical model is proposed for the (0,0,1) superlattice manganite system (LaMnO$_3$)$_n$(SrMnO$_3$)$_m$. The model includes the electron-electron, electron-phonon, and cooperative Jahn-Teller interactions. It is solved using a version of single-site the dynamical mean field approximation generalized to incorporate the cooperative Jahn-Teller ...

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)
