Abstract

We study the magnetoresistance (MR) of the quasi-2-D electron liquid at the interface that forms between SrTiO₃and LaAlO₃as a function of the magnitude and orientation of the magnetic field. We find that at T ≥ 60 K, the MR is described by a+b cos²θ+c sin ²θ cos² φ, where θ is the angle between the field and the film normal and φ is the angle between the in-plane component of the field and the current. For θ=0° (field perpendicular to the plane), we show that the MR obeys Kohler's rule while for θ=90° (field in the plane) the MR is significantly smaller, and it is almost temperature independent, suggesting it is dominated by interface scattering.
