This review addresses the method of explicit calculations of interatomic exchange
interactions of magnetic materials. This involves exchange mechanisms normally referred to …

The ability to switch ferroics (ferro-, ferri-, antiferromagnets, ferroelectrics, multiferroics)
between two stable bit states is one of the keystones of modern data storage technology …

The purpose of this book is to provide a theoretical foundation and an understanding of
atomistic spin-dynamics (ASD), and to give examples of where the atomistic Landau-Lifshitz …

The strongest interaction between microscopic spins in magnetic materials is the exchange
interaction J ex. Therefore, ultrafast control of J ex holds the promise to control spins on …

Ultrafast non-thermal manipulation of magnetization by light relies on either indirect coupling
of the electric field component of the light with spins via spin-orbit interaction or direct …

In this paper we present an accurate numerical scheme for extracting interatomic exchange
parameters (J ij) of strongly correlated systems, based on first-principles full-potential …

The understanding of how the sub-nanoscale exchange interaction evolves in macroscale
correlations and ordered phases of matter, such as magnetism and superconductivity …

Scalar spin chirality, a three-body spin correlation that breaks time-reversal symmetry, is
revealed to couple directly to circularly polarized laser. This is shown by the Floquet …

In recent years, the optical control of exchange interactions has emerged as an exciting new
direction in the study of the ultrafast optical control of magnetic order. Here we review recent …

We investigate how fast and how effective photocarrier excitation can modify the exchange
interaction J ex in the prototype Mott-Hubbard insulator. We demonstrate an ultrafast …
