Efficient Terahertz Generation from CoPt-based Terahertz Emitters via Orbital-to-Charge Conversion
Yongshan Liu, Yong Xu, Albert Fert +5
Orbitronics devices operate by manipulating orbitally-polarized currents. Recent studies have shown that these orbital currents can be excited by femtosecond laser pulses in ferrom…

Giant orbit-to-charge conversion induced via the inverse orbital Hall effect
Renyou Xu, Hui Zhang, Yuhao Jiang +13
We investigate the orbit-to-charge conversion in YIG/Pt/nonmagnetic material (NM) trilayer heterostructures. With the additional Ru layer on the top of YIG/Pt stacks, the charge cu…

Orbitronics: Light-induced Orbit Currents in Terahertz Emission Experiments
Yong Xu, Fan Zhang, Albert Fert +6
Orbitronics is based on the use of orbit currents as information carriers. Up to now, orbit currents were created from the conversion of charge or spin currents, and inversely, the…
