Figure 5. Magneto-transport studies of 6 uc LSTO/STO heterostructure.
Magnetoresistance of (a) 6 uc LSTO/STO heterostructures and (b) 60 uc LSTO/STO heterostructures under different back gate voltages. Weak anti-localization is observed in 6 uc LSTO/STO heterostructures, indicating the existence of spin-orbital coupling. (c) Hikami–Larkin–Nagaoka (HLN) fitting on the spin-orbital coupling in 6 uc LSTO/STO heterostructures under different gate voltages.
