Orbitronics is a field that explores the use of orbital currents as information carriers. This study demonstrates that orbital currents can be generated by femtosecond light pulses on nickel (Ni) and detected through their conversion into charge currents, resulting in terahertz (THz) emission. In multilayers combining Ni with oxides and nonmagnetic metals like copper (Cu), the orbital currents dominate over light-induced spin currents in Ni-based systems, while only spin currents are detectable in CoFeB-based systems. The time delays of THz pulses provide insights into the velocity and propagation length of orbital carriers. The findings open new avenues for orbitronic devices, including the development of orbitronic terahertz devices. The study also highlights the importance of orbital currents in condensed matter physics and their potential applications in future magnetic memory devices.Orbitronics is a field that explores the use of orbital currents as information carriers.
