  Resistance as a function of temperature down to 20mK and magnetic fields up
to 18T for various carrier concentrations is measured for nanowires made from
the SrTiO3/LaAlO3 interface using a hard mask shadow deposition technique. The
narrow width of the wires (of the order of 50nm) allows us to separate out the
magnetic effects from the dominant superconducting ones at low magnetic fields.
At this regime hysteresis loops are observed along with the superconducting
transition. From our data analysis we find that the magnetic order probed by
the giant magnetoresistance (GMR) effect vanishes at TCurie = 954 mK. This
order is not a simple ferromagnetic state but consists of domains with opposite
magnetization having a preferred in-plane orientation.
