An electron in a solid, that is, bound to or nearly localized on the specific atomic site, has
three attributes: charge, spin, and orbital. The orbital represents the shape of the electron …

In this article, we present an in-depth review of the phenomenon of negative magnetization
(or magnetization sign reversal) with an up-to-date literature. We have described numerous …

Describing all aspects of the physics of transition metal compounds, this book provides a
comprehensive overview of this unique and diverse class of solids. Beginning with the basic …

The prospect of controlling the magnetization (M) of a material is of great importance from
the viewpoints of fundamental physics and future applications of emerging spintronics. A …

We report an experimental and computational study of single-crystal NdFeO 3, which
features two inequivalent magnetic sublattices, namely, Fe and Nd sublattices that are …

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 …

A systematic microscopic theory of magnetically induced ferroelectricity and lattice
modulation is presented for various electron configurations of Mott-insulating transition metal …

We show the design and preparation of a novel type of magnet exhibiting two compensation
temperatures; ie, the spontaneous magnetization changes its sign twice with changing …

The global phase diagram for the spin and orbital ordering has been investigated for
perovskite-type R VO 3 (R being a rare-earth ion or Y) by measurements of specific heat …

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 …
