a Sheet resistance \({R}_{s}\) as a function of temperature along two in-plane orthogonal directions. The inset shows the temperature-dependent carrier density and mobility obtained by traditional Hall measurements in the direction \([1\bar{1}0]\). b, c Circular photogalvanic effect studies of (112)-LaAlO3/SrTiO3 in the in-plane direction (b), \([1\bar{1}0]\) and (c), \([11\bar{1}]\). d Kerr rotation \({\theta }_{{{\rm{K}}}}\) as a function of current amplitude in directions of \(\left[1\bar{1}0\right]\) and \([11\bar{1}]\). e Mapping images of \({\theta }_{{{\rm{K}}}}\) across a 10 \({{\rm{\mu }}}{{\rm{m}}}\)-width channel at a current density of \({J}^{\omega }=2{{\rm{A}}}/{{\rm{m}}}\) (20 \({{\rm{\mu }}}\)A) in the direction of \(\left[1\bar{1}0\right]\). f The line scan of \({\theta }_{{{\rm{K}}}}\) in the direction of \(\left[1\bar{1}0\right]\) and \(\left[11\bar{1}\right]\) at a current density of \({J}^{\omega }=2{{\rm{A}}}/{{\rm{m}}}\). The error bar of each data point is statistically calculated over 600 measurement values.
