Optimized Spin-Terahertz Emitters based on FM/NM Structures
Terahertz electromagnetic emission is useful for many applications, including imaging and spectroscopy. In this paper, the emitter is optimized with respect to layer thickness by modeling the terahertz emission field. the effect of sapphire, glass, W and MgO substrates on the optimal thickness of the Fe/Pt spinterahertz emitter was investigated. The model used in this paper considers spin polarization, spin scattering and spin accumulation in Fe and Pt layers, and the electrical and optical properties of the layers.
