Spin Hall effect in the high-resistivity high-entropy alloy AlCrMoW
Jyoti Yadav, Felix Janus, Tiago de Oliveira Schneider +3
We study thin films of the high-entropy alloy system Al(CrMoW), grown on Ta seed layers by magnetron co-sputtering. Between and , a resistivity larger…
Enhanced THz emission from spintronic emitters with Pt-Al alloys
Felix Janus, Nicolas Beermann, Jyoti Yadav +5
Platinum (Pt) is the element with the largest spin Hall conductivity and is known as the most efficient spin-to-charge conversion material in spintronic THz emitters. By alloying w…
Emergent spin Hall conductivity in Tantalum-Rhenium alloys
Felix Janus, Jyoti Yadav, Nicolas Beermann +5
We investigate the spin Hall conductivity (SHC) of a composition series of a Ta-Re bcc solid solution. At approximately 60 at.% Ta the Ta-Re alloy features an SHC similar to bcc-W,…
Efficient Spintronic THz Emitters Without External Magnetic Field
Amir Khan, Nicolas Sylvester Beermann, Shalini Sharma +4
We investigate the performance of state-of-the-art spintronic THz emitters (W or Ta)/CoFeB/Pt with non-magnetic underlayer deposited using oblique angle deposition. The THz emissio…
