Autor: Orlova T. S., Skiba N. V., Mavlyutov A. M., Murashkin M. Yu., Valiev R. Z., Gutkin M. Yu.

Publikováno v: Reviews on Advanced Materials Science, Vol 57, Iss 2, Pp 224-240 (2018)

The influence of low temperature annealing and subsequent deformation on microstructure, strength and ductility was investigated for the first time for high pressure torsion (HPT) processed commercially pure Al. Extremely high increases in the conven

Spectral bootstrap confidence bands for L\'evy-driven moving average processes

Autor: Belomestny, D., Ivanova, E., Orlova, T.

In this paper we study the problem of constructing bootstrap confidence intervals for the L\'evy density of the driving L\'evy process based on high-frequency observations of a L\'evy-driven moving average processes. Using a spectral estimator of the

Topological response of the anomalous Hall effect in MnBi2Te4 due to magnetic canting

Autor: Bac, S. -K., Koller, K., Lux, F., Wang, J., Riney, L., Borisiak, K., Powers, W., Zhukovskyi, M., Orlova, T., Dobrowolska, M., Furdyna, J. K., Dilley, N. R., Rokhinson, L. P., Mokrousov, Y., McQueeney, R. J., Heinonen, O., Liu, X., Assaf, B. A.

Three-dimensional (3D) compensated MnBi2Te4 is antiferromagnetic, but undergoes a spin-flop transition at intermediate fields, resulting in a canted phase before saturation. In this work, we experimentally show that the anomalous Hall effect (AHE) in

Weak antilocalization beyond the fully diffusive regime in Pb1-xSnxSe topological quantum wells

Autor: Wang, Jiashu, Liu, X., Bunker, C., Riney, L., Qing, B., Bac, S. K., Zhukovskyi, M., Orlova, T., Rouvimov, S., Dobrowolska, M., Furdyna, J. K., Assaf, B. A.

We report the measurements and analysis of weak antilocalization (WAL) in Pb1-xSnxSe topological quantum wells in a new regime where the elastic scattering length is larger than the magnetic length. We achieve this regime through the development of h
