a Electrical resistance (Rs) as a function of temperature at zero magnetic field for two representative a-YAlO3/KTaO3 heterostructures (Samples #1 and #2). Low temperature dependence of Rs is illustrated in the inset of a. Magnetoresistance for fields b parallel and c perpendicular to the plane surface of Sample #1. d Temperature dependence of the upper critical field μ0Hc2 (μ0H\({}_{c2}^{\parallel }\) for the in-plane field along the \([11\bar{2}]\)-axis shown in Fig. 1d and μ0H\({}_{c2}^{\perp }\) for the out-of-plane field).
