NMR in Ferromagnetic Manganites [PDF]

open access: yes, 2004
The conditions for observing NMR on the $\text{}^{55}$Mn nuclei in the ferromagnetic manganites are specified and the information which may be extracted from this NMR are discussed. As examples, the study of the order of the magnetic phase transition and

Ferroelectric Topological Defects in Hexagonal Manganites. [PDF]

open access: yesMaterials (Basel)
Hexagonal rare-earth manganites, as prototypical improper ferroelectrics in which structural distortions give rise to ferroelectricity, exhibit unique physical phenomena that are absent in conventional proper ferroelectrics.

Fast Two-stage Protector Against Electromagnetic Pulse Based on Electroresistance Effect in Polycrystalline La-Sr(Ca)-Mn-O Films

open access: yesMedžiagotyra, 2014
The electroresistance (ER) effect in polycrystalline films of La0.83Sr0.17MnO3 and La0.7Ca0.3MnO3 was investigated in the temperature range of (5 – 290) K using high power sub-nanosecond rise time electrical pulses with amplitude up to 1 kV.

The electronic structure of colossal magnetoresistive manganites [PDF]

open access: yes, 1998
The ferromagnetic manganites A1-xBxMnO3 (A a trivalent element and B divalent) have been the subject of intensive study in the past few years. These manganites exhibit colossal magnetoresistance (CMR), i.e.

Strain effects in perovskite manganites

open access: yes, 2007
Colossal magnetoresistance (CMR) - the dramatic reduction of electrical resistivity in a magnetic field and charge ordering (CO) in rare earth manganites of the type Ln(1-x)A(x)MnO(3) [Ln: rare earth, A: divalent cation] are manifestations of the ...

INTRINSIC ELECTRON LOCALIZATION IN MANGANITES

open access: yes, 2010
We mention here an unusual disorder effect in manganites, namely the ubiquitous hopping behavior for electron transport observed in them over a wide range of doping.

Spin Excitations in Doped Manganites [PDF]

open access: yes, 2000
We generalize the double exchange to describe holes doped in degenerate e$\text{}_{g}$ orbitals in La$\text{}_{1-x}$A$\text{}_{x}$MnO$\text{}_{3}$ manganites, where A are divalent alkaline earth ions. Assuming an orbital liquid of disordered e$\text{}_{g}
