A direct electrical current can drive high-frequency oscillations of the magnetization of a nanomagnet. A current-tunable microwave oscillator has now been demonstrated that shows large-amplitude ...

Scientists successfully observed 'orbital pumping', a new phenomenon in which orbital currents are generated from the precession of magnetization in magnetic materials. The discovery could provide the ...

(Nanowerk News) Ultrafast non-equilibrium magnetization in correlated spin systems is extensively studied in recent years. At both fundamental and application levels, ultrafast laser pulse excitation ...
