This review compiles results of experimental and theoretical studies on thin films and
quantum structures of semiconductors with randomly distributed Mn ions, which exhibit …

The interaction of subpicosecond laser pulses with magnetically ordered materials has
developed into a fascinating research topic in modern magnetism. From the discovery of …

This article reviews the current status of spin dynamics in semiconductors which has
achieved much progress in the recent years due to the fast growing field of semiconductor …

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 …

The technological demand to push the gigahertz (109 hertz) switching speed limit of today's
magnetic memory and logic devices into the terahertz (1012 hertz) regime underlies the …

The microscopic origin of ultrafast modification of the ratio between the symmetric (J) and
antisymmetric (D) exchange interaction in antiferromagnetic iron oxides is revealed, using …

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 report on the nonlinear magnetization dynamics of a HoFeO 3 crystal induced by a
strong terahertz magnetic field resonantly enhanced with a split ring resonator and …

The development of two-dimensional (2D) magnetism is driven not only by the interest of low-
dimensional physics but also by potential applications in high-density miniaturized …

We review the first decade of extensive optical studies of ferromagnetic, III-Mn-V diluted
magnetic semiconductors. Mn introduces holes and local moments to the III–V host, which …
