Ultrathin two-dimensional superconductivity with strong spin-orbit coupling.
We report on a study of epitaxially grown ultrathin Pb films that are only a few atoms thick and have parallel critical magnetic fields much higher than the expected limit set by the interaction of electron spins with a magnetic field, that is, the Clogston-Chandrasekhar limit. The epitaxial thin films are classified as dirty-limit superconductors because their mean-free paths, which are limite...
متن کاملSpin-orbit scattering and quantum metallicity in ultrathin Be films
We compare and contrast the low-temperature magnetotransport properties of ultrathin, insulating Be films with and without spin-orbit scattering SOS . Beryllium films have very little intrinsic SOS, but by “dusting” them with submonolayer coverages of Au, one can introduce a well-controlled SOS rate. Pure Be films with sheet resistance R RQ exhibit a low-temperature negative magnetoresistance M...
متن کاملAnisotropic Polar Magneto-Optic Kerr Effect of Ultrathin Fe/GaAs(001) Layers due to Interfacial Spin-Orbit Interaction.
We report the observation of the anisotropic polar magneto-optical Kerr effect in thin layers of epitaxial Fe/GaAs(001) at room temperature. A clear twofold symmetry of the Kerr rotation angle depending on the orientation of the linear polarization of the probing laser beam with respect to the crystallographic directions of the sample is detected for ultrathin magnetic films saturated out of th...
متن کاملNanowire spin torque oscillator driven by spin orbit torques.
Spin torque from spin current applied to a nanoscale region of a ferromagnet can act as negative magnetic damping and thereby excite self-oscillations of its magnetization. In contrast, spin torque uniformly applied to the magnetization of an extended ferromagnetic film does not generate self-oscillatory magnetic dynamics but leads to reduction of the saturation magnetization. Here we report st...
متن کاملIntrinsic spin torque without spin-orbit coupling.
We derive an intrinsic contribution to the non-adiabatic spin torque for non-uniform magnetic textures. It differs from previously considered contributions in several ways and can be the dominant contribution in some models. It does not depend on the change in occupation of the electron states due to the current flow but rather is due to the perturbation of the electronic states when an electri...
