Fig. 3: Spin–orbit coupling strength analysis.

(Color online) Schematic of the connection geometry for magnetoresistance (Rxx) measurements for magnetic field applied (a) out-of-plane and b in the plane. c Magnetoconductance plot of 4 ml sample as a function of magnetic field showing weak anti-localization due to high spin–orbit coupling along with the fitting done without the Kohler term (black line) and the fit including the Kohler term (cyan line). d Comparative plot of BSO vs. gate voltage for STO and KTO based systems.
