摘要：
The sheet resistance as a function of temperature, magnetic field and its orientation for atomically flat SrTiO3/LaAlO3 interfaces with carrier densities of similar to 3 x 10(13) cm(-2) is reported. At low magnetic fields superconductivity is observed below 130 mK. The temperature dependence of the high field magnetoresistance and its strong anisotropy suggest possible magnetic ordering below 35 K. The origin of this ordering and its possible relation to superconductivity are discussed.
