摘要

The ion irradiation technique is utilized to modify the surface structure of transition metal oxides (TMOs), including SrTiO3 and TiO2. After low-energy Ar+ ion bombardment, oxygen vacancies are introduced into the TMO surface layer, and their resistance decreases with increasing irradiation time. For the two oxides, the temperature-dependent resistivity exhibits different conducting behaviors. Due to the generation of an electron-doped quasi-2D surface layer, the voltage signals of the inverse Rashba-Edelstein effect are extracted in the ion-irradiated TMO with ferromagnetic permalloy films, and the spin transport parameters are respectively calculated from the ferromagnetic resonance measurement data.
