Indication of novel magnetoresistance mechanism in (Bi,Sb)(Te,Se) 3D topological insulator thin films
N. P. Stepina, A. O. Bazhenov, A. V. Shumilin +5
Electron states with the spin-momentum-locked Dirac dispersion at the surface of a three-dimensional (3D) topological insulator are known to lead to weak antilocalization (WAL), i.…
Tunneling magnetoresistance in ensembles of ferromagnetic granules with exchange interaction and random easy axes of magnetic anisotropy
Y. M. Beltukov, V. I. Kozub, A. V. Shumilin +1
We study the tunneling magnetoresistance in the ensembles of ferromagnetic granules with random easy axes of magnetic anisotropy taking into account the exchange interaction betwee…

Universal behavior of magnetoresistance in quantum dot arrays with different degree of disorder
N. P. Stepina, E. S. Koptev, A. G. Pogosov +4
Magnetoresistance in two-dimensional array of Ge/Si quantum dots was studied in a wide range of zero-magnetic field conductances, where the transport regime changes from hopping to…
Nonlinear high-frequency hopping conduction in two-dimensional arrays of Ge-in-Si quantum dots: Acoustic methods
I. L. Drichko, A. M. Diakonov, V. A. Malysh +6
Using acoustic methods we have measured nonlinear AC conductance in 2D arrays of Ge-in-Si quantum dots. The combination of experimental results and modeling of AC conductance of a…
