High field magneto-transport in two-dimensional electron gas LaAlO3/SrTiO3
The transport properties of the complex oxide LaAlO3/SrTiO3 interface are investigated under a high magnetic field (55 T). Small oscillations of the magnetoresistance with altered periodicity are observed when plotted versus the inverse magnetic field. We attribute this effect to Rashba spin-orbit c...

| description | The transport properties of the complex oxide LaAlO3/SrTiO3 interface are investigated under a high magnetic field (55 T). Small oscillations of the magnetoresistance with altered periodicity are observed when plotted versus the inverse magnetic field. We attribute this effect to Rashba spin-orbit coupling which remains consistent with large negative magnetoresistance when the field is parallel to the sample plane. A large inconsistency between the carrier density extracted from Shubnikov-de Haas analysis and from the Hall effect is explained by the contribution to transport of at least two bands with different mobilities. |
