Orbital exchange-mediated current control of magnetism

This work predicts the current-induced control of magnetism by orbital exchange interaction and provides formal framework treating the orbital exchange interaction, not only limited to conventional ferromagnetic systems.

Spin currents and spin–orbit torques in ferromagnetic trilayers

Spin–orbit torques are reported in ferromagnetic trilayers that lead to the switching of perpendicular magnetizations without an external magnetic field.

Magnetic control of phonon transport in magnetic insulator thulium iron garnet

The coupling between magnons and phonons is an important aspect of condensed matter physics, but most research is related to magnon relaxation effects rather than the impact on phonon transport. Here, the effect of magnon-phonon coupling on phonon excitation, relaxation, and transport is investigated by time-resolved magneto-optical reflectometry.

Efficient conversion of orbital Hall current to spin current for spin-orbit torque switching

Manipulation of the magnetization is of major importance in spintronics. The authors demonstrate that an electric field triggers a transverse flow of orbital moment: the so-called orbital Hall effect. This enables the efficient magnetization control, holding the promise for fast and miniaturized memories and sensors.
