Strongly correlated materials are profoundly affected by the repulsive electron‐electron
interaction. This stands in contrast to many commonly used materials such as silicon and …

Magnetotactic bacteria, known to produce magnetic nanocrystals with uniform shapes and
sizes at physiological conditions, serve as an inspiration and source of a number of …

Experimental studies of compressed matter are now routinely conducted at pressures
exceeding 1 mln atm (100 GPa) and occasionally at pressures greater than 10 mln atm (1 …

Recently, multiferroic materials, that is, materials that possess two or more ferroic properties,
such as spontaneous electric polarization and magnetization in the same phase, have …

Multiferroic heterostructures comprising ferroelectric and ferro (ferri) magnetic constituents
have recently attracted considerable interest due to the strong coupling between magnetic …

The metal–insulator transition driven by electronic correlations is one of the most
fundamental concepts in condensed matter. In mixed-valence compounds, this transition is …

In this paper, the structural, morphological, electrical and dielectric properties of hard/soft
ferrite nanocomposites (NCs) of CoFe 2 O 4/(NiSc 0.03 Fe 1.97 O 4) x (where x= 1, 2, 3, 4, 5) …

Abstract Magnetite (Fe3O4), an archetypal transition-metal oxide, has been used for
thousands of years, from lodestones in primitive compasses to a candidate material for …

The Verwey phase transition in magnetite has been analyzed using the group theory
methods. It is found that two order parameters with the symmetries X 3 and Δ 5 induce the …
