The Orbital Hall effect, originating from materials with weak spin-orbit coupling, has gained significant interest for spin-orbitronic applications. This paper demonstrates the inverse orbital Hall effect (IOHE) and observes orbitronic terahertz (THz) emission in Ti and Mn materials. Spin-orbit transition in the ferromagnetic layer converts the generated orbital current into charge current via IOHE in the Ti and Mn layers. A W layer further enhances orbitronic THz emission. The emission is manipulated by combining IOHE and the inverse spin Hall effect in various sample configurations. The findings unveil the underlying physics and offer pathways for developing spin-orbitronic devices and THz emitters.
