We investigated the magnetotransport properties of mesoscopic platinum nanostructures (wires and rings) with sub-100 nm lateral dimensions at very low temperatures. Despite the strong spin-orbit interaction in platinum, oscillations of the conductance as a function of the external magnetic field due to quantum interference effects was found to appear. The oscillation was decomposed into Aharonov-Bohm periodic oscillations and aperiodic fluctuations of the conductance due to a magnetic flux…

Spin Hall current driven by quantum interferences in mesoscopic Rashba rings.
We propose an all-electrical nanostructure where pure spin current is induced in the transverse voltage probes attached to a quantum-coherent ballistic one-dimensional ring when unpolarized charge
Universal conductance fluctuations and localization effects in InN nanowires connected in parallel
The low-temperature quantum transport of InN nanowires grown by plasma-assisted molecular beam epitaxy is investigated. Two sets of nanowires with diameters of 100 and 45 nm originating from two
Universal conductance fluctuations and phase-coherent transport in a semiconductor Bi2O2Se nanoplate with strong spin-orbit interaction.
A strong reduction in amplitude of the universal conductance fluctuations is found and the results agree with the analysis assuming strong spin-orbit interaction in the Bi2O2Se nanoplate, consistent with the result obtained from the weak localization analysis.
Spin-Orbit Interaction and Magnetoresistance in the Two Dimensional Random System
Effect of the spin-orbit interaction is studied for the random potential scattering in two dimensions by the renormalization group method. It is shown that the localization behaviors are classified

Weak localization in thin films: a time-of-flight experiment with conduction electrons
Abstract The resistance of two-dimensional electron systems such as thin disordered films shows deviations from Boltzmann theory, which are caused by quantum corrections and are called “weak
We propose a spin-interference device which works even without any ferromagnetic electrodes and any external magnetic field. The interference can be expected in the Aharonov–Bohm (AB) ring with a
