Terahertz emission from $\alpha$-W/CoFe epitaxial spintronic emitters

Venkatesh Mottamchetty, Rimantas Brucas, Anna L. Ravensburg +8

We report efficient terahertz (THz) generation in epitaxial $\alpha$-W/Co${}_{60}$Fe${}_{40}$ spintronic emitters. Two types of emitters have been investigated; epitaxial $\alpha$-W$(110)$/Co$_{…
