Ilyas et al. demonstrated the efficient manipulation of the magnetic ground state in layered magnets through non-thermal pathways using terahertz light and established regions near critical points with enhanced order parameter fluctuations as promising areas to search for metastable hidden quantum states.

Physicists at MIT have directly stimulated atoms in an antiferromagnetic material using a terahertz laser, a light source that oscillates more than a trillion...

Structure of SOT spin-LED: controlling the intensity of emitted light and charge current is the basis of transferring and processing information; by contrast, robust information storage and magnetic random-access memories are implemented using the spin of the carrier and the associated magnetization in ferromagnets; the missing link between the respective disciplines of photonics, electronics and spintronics is to modulate the circular polarization of the emitted light, rather than its intensity, by electrically controlled magnetization; Dainone et al. demonstrated that this missing link is established at room temperature and zero applied magnetic field in light-emitting diodes through the transfer of angular momentum between photons, electrons and ferromagnets.
