Large modulation of the Shubnikov–de Haas oscillations by the Rashba interaction at the LaAlO3/SrTiO3 interface
We investigate the two-dimensional Fermi surface of high-mobility LaAlO _3 /SrTiO _3 interfaces using Shubnikov-de Haas oscillations. Our analysis of the oscillation pattern underscores the key role played by the Rashba spin–orbit interaction brought about by the breaking of inversion symmetry, as w...

| description | We investigate the two-dimensional Fermi surface of high-mobility LaAlO _3 /SrTiO _3 interfaces using Shubnikov-de Haas oscillations. Our analysis of the oscillation pattern underscores the key role played by the Rashba spin–orbit interaction brought about by the breaking of inversion symmetry, as well as the dominant contribution of the heavy d _xz / d _yz orbitals on electrical transport. We furthermore bring into light the complex evolution of the oscillations with the carrier density, which is tuned by the field effect. |
