Abstract

The transverse magnetic moment and torque observed by Li et al. (Nat. Phys. 7, 762 (6)) in the LaAlO3/SrTiO3 interface is claimed to have a purely kinetic origin. To explain the data, we describe the electronic state by a two-component order parameter with zero helicity. The zero helicity state breaks the spatial reflection symmetry of the kinetic energy according to the mechanism described here. The resulting state is a lattice of vortex-skyrmions that result in a transverse magnetization due to the asymmetry in the mass and thickness anisotropy between the two sides of the interface.
