Abstract:
An investigation was made of THz radiation in the Fe/Mo magnetic junction arising from the pumping by a high-density current of the upper spin subband in the induced ferromagnetism layer in Mo. The tensor character of the exchange interaction constant at the Fe/Mo interface, associated with the presence of the Dzyaloshinsky–Moriya interaction, promotes radiative relaxation.
Keywords:
THz radiation, spin-polarized current, anisotropic exchange interaction, Dzyaloshinsky–Moriya interaction.
