Multiferroics, defined for those multifunctional materials in which two or more kinds of
fundamental ferroicities coexist, have become one of the hottest topics of condensed matter …

Magnetoelectric multiferroics is an old but emerging class of materials that combine coupled
electric and magnetic dipole order. In these materials, ferroelectric and magnetic …

With the perovskite multiferroic R Mn O 3 (R= Gd, Tb, Dy) as guidance, we argue that the
Dzyaloshinskii-Moriya interaction (DMI) provides the microscopic mechanism for the …

Magnetodielectric materials are characterized by a strong coupling of the magnetic and
dielectric properties and, in rare cases, simultaneously show both magnetic and polar order …

We present an overview of the current interest in non-collinear magnetism in multiferroic
perovskite crystals. We first describe the different microscopic mechanisms giving rise to the …

We develop a theory of collective mode dynamics in the helical magnets coupled to electric
polarization via spin-orbit interaction. The low-lying modes associated with the …

We study theoretically the electric polarization induced by noncollinear spin configurations
in the limit of strong Hund coupling. We employ a model of two magnetic ions sandwiching …

Orthorhombically distorted perovskite manganites, R Mn O 3 with R being a trivalent rare-
earth ion, exhibit a variety of magnetic and electric phases including multiferroic (ie …

Lattice modulation and magnetic structures in magnetoelectric compounds Tb 1-x Dy x MnO
3 have been studied around the ferroelectric (FE) Curie temperature TC by x-ray and …

We report on structural, magnetic, dielectric, and thermodynamic properties of Eu 1− x Y x
Mn O 3 for Y doping levels 0⩽ x< 1. This system resembles the multiferroic perovskite …
