Anisotropic magneto-transport effects at SrTiO33 interfaces
Abstract
The resistivity as a function of temperature, magnetic field and its orientation for atomically flat SrTiO33 interfaces with carrier densities of ~3*1013 cm-2 is reported. At low magnetic fields superconductivity is observed below 130mK. The temperature dependence of the high field magnetoresistance and its strong anisotropy suggest possible magnetic ordering below 35K. The origin of this ordering and its possible relation to superconductivity are discussed.
