Transport properties in BTO 9/3/10 and STO 9/3/10. a Temperature dependence of longitudinal resistivity ρ for the BTO 9/3/10, STO 9/3/10, 3 u.c. SRO, and 60 u.c. SRO films. The BTO 9/3/10 has low resistivity compared to STO 9/3/10 and bare 3 u.c. SRO film. b Temperature dependence of longitudinal resistivity of BTO 9/3/10 and STO 9/3/10 under various magnetic field. Metallic behavior is observed at all fields. Inset: temperature dependence of the derivative dρ/dT of BTO 9/3/10. A clear kink around 125 K is the typical feature of magnetic transition in SRO. c Magnetoresistance of BTO 9/3/10 at different temperatures. The butterfly loop indicates ferromagnetism in BTO 9/3/10
