Terahertz Radiation in the Fe/Mo Magnetic Transition

The terahertz radiation in the Fe/Mo magnetic transition, which occurs when pumping the upper spin subzone in the Fe/Mo interface with a high-density current, has been investigated. The tensor character of the exchange interaction constant on the Fe/Mo interface associated with the presence of the D...

Description
Summary:The terahertz radiation in the Fe/Mo magnetic transition, which occurs when pumping the upper spin subzone in the Fe/Mo interface with a high-density current, has been investigated. The tensor character of the exchange interaction constant on the Fe/Mo interface associated with the presence of the Dzyaloshinskii–Moriya interaction, contributes to radiative relaxation.
