The author reviews the present understanding of the hole-mediated ferromagnetism in
magnetically doped semiconductors and oxides as well as the origin of high temperature …

We systematically investigate the crystal structure, magneto-optical properties,
magnetization, and magnetotransport properties of a new ferromagnetic semiconductor (G a …

Transition metal dichalcogenides (TMDs) are interesting for understanding the fundamental
physics of two-dimensional (2D) materials as well as for applications to many emerging …

In systems with strong spin-orbit coupling, the relationship between spin transfer torque and
the divergence of the spin current is generalized to a relation between spin transfer torques …

A new class of devices based on topological insulators (TI) can be achieved by the direct
engineering of the time-reversal-symmetry (TRS) protected surface states. In the meantime …

The origin of magnetism in undoped MgO has been studied based on density functional
theory. It is shown that Mg vacancies can induce local moments in MgO while O vacancies …

The interplay between spin, charge and orbital degrees of freedom has led to the
development of spintronic devices such as spin–torque oscillators and spin-transfer torque …

Many theoretical and experimental studies deal with the realization of room‐temperature
ferromagnetism in dilute magnetic semiconductors (DMS). However, a detailed quantitative …

Intraband and interband contributions to the current-driven spin-orbit torque in magnetic
materials lacking inversion symmetry are theoretically studied using the Kubo formula. In …

Two-dimensional magnetic materials (2DMMs) are significant not only for studies on the
nature of 2D long-range magnetic order but also for future spintronic devices. Of particular …
