Shaping THz emission spectra by using sub-wavelength nanopatterned spintronic THz emitters
Bikash Das-Mohapatra, Reza Rouzegar, Evangelos Th. Papaioannou +2
We show in theory and experiment that in periodically patterned spintronic THz emitters (STE), charge dynamics can modify the emission spectrum in a well-controlled way. Characteri…
Terahertz spin conductance probes of coherent and incoherent spin tunneling through MgO tunnel junctions
R. Rouzegar, M. A. Wahada, A. L. Chekhov +9
We study femtosecond spin currents through MgO tunneling barriers in CoFeB(2 nm)|MgO()|Pt(2 nm) stacks by terahertz emission spectroscopy. To obtain transport information indepe…
Time-domain observation of ballistic orbital-angular-momentum currents with giant relaxation length in tungsten
Tom S. Seifert, Dongwook Go, Hiroki Hayashi +5
The emerging field of orbitronics exploits the electron orbital momentum . Compared to spin-polarized electrons, may allow magnetic-information transfera w…
