Open AccessMesoscopic theory of defect ordering–disordering transitions in thin oxide films
Ordering of mobile defects in functional materials can give rise to fundamentally new phases possessing ferroic and multiferroic functionalities. Here we develop the Landau theory for strain induced ordering o...

Open AccessFerromagnetic-like behavior of Bi0.9La0.1FeO3–KBr nanocomposites
We studied magnetostatic response of the Bi0.9La0.1FeO3– KBr composites (BLFO-KBr) consisting of nanosized (≈100 nm) ferrite Bi0.9La0.1FeO3 (BLFO) conjugated with fine grinded ionic conducting KBr. When the fract...

Fixed volume effect on polar properties and phase diagrams of ferroelectric semi-ellipsoidal nanoparticles
For advanced applications in modern industry, it is very important to reduce the volume of ferroelectric nanoparticles without serious deterioration of their polar properties. In many practically important ca...

Open AccessThermodynamic potential and phase diagram for multiferroic bismuth ferrite (BiFeO 3 )
We construct a Landau–Ginzburg thermodynamic potential, and the corresponding phase diagram for pristine and slightly doped bismuth ferrite, a ferroelectric antiferromagnet at room temperature. The potential i...
