A detailed study of the electronic structure and magnetic configurations of the 50% hole-doped double-layered manganite LaSr2Mn2O7 is presented. We demonstrate that the on-site Coulomb correlation (U) of Mn d electrons (i) significantly modifies the electronic structure, magnetic ordering (from FM to AFM), and interlayer exchange interactions, and (ii) promotes strong anisotropy in electrical t...

Colossal electroresistance (CER) has been observed in the ferromagnetic insulating (FMI) state of a manganite. Notably, the CER in the FMI state occurs in the absence of magnetoresistance (MR). Measurements of electroresistance (ER) and current induced resistivity switching have been performed in the ferromagnetic insulating state of a single crystal manganite of composition Nd0.7Pb0.3MnO3 (NPM...

We study the origin of the magnetoelectric coupling in manganite films on ferroelectric substrates. We find large magnetoelectric coupling in La0.7Ca0.3MnO3/BaTiO3 ultra-thin films in experiments based on the converse magnetoelectric effect. The magnetization changes by around 30-40% upon applying electric fields on the order of 1 kV/cm to the BaTiO3 substrate, corresponding to magnetoelectric ...

Based on the data of thermogravimetric analysis values oxygen index (3–δ) in manganite La 0.7 Sr 0.3 Mn 0.9 Fe 0.1 O 3-δ composition, obtained by solid-phase reaction technique, have been calculated. The sorption-desorption curves showed that processes release and absorption at p 2 = 10 Pa 400 are not reversible. minima derivative dδ/d t f ( T ) corresponding to maxima extraction rate indicate ...
