Bifurcations in Josephson junction coupled to the nanomagnet

Nashaat, M.; Sameh, M.; Kulikov, K. V.; Shukrinov, Yury M.; Botha A.E., / (Publishing house of Nizhniy Novgorod State University, 2022)

In this study, we consider voltage biased Josephson junction coupled to nanomagnet. We investigate the period doubling bifurcation due to interplay between superconducting phase and magnetization in Josephson junction. We ...
Nonlinearity, locking, and chaos in anomalous Josephson junctions

Shukrinov, Yury M.; Rahmonov, I. R.; Kulikov, K. V.; Abdelmoneim, S. A.; Nashaat, M.; Janalizadeh, A.; Kolahchi, M. R.; Tekic, J.; Botha A.E., /; Tekic, J (Publishing house of Nizhniy Novgorod State University, 2023)

The effects of external electromagnetic radiation on the synchronization of the magnetization precession and Josephson oscillations in the phi-zero junction are investigated. Their manifestation in the magnetization dynamics ...
Semiconductor radiation detectors for current and future applications

Moloi, Sabata (2023-11-29)
Adsorption mechanism and modeling of radionuclides and heavy metals onto ZnO nanoparticles: a review

Akpomie, Kovo G.; Conradie, Jeanet; Adegoke, Kayode A.; Oyedotun, Kabir O.; Ighalo, Joshua. O.; Amaku, James F.; Olisah, Chijioke; Adeola, Adedapo O.; Iwuozor, Kingsley O. (2022-11-27)

Abstract The contamination of environmental waters with heavy metals and radionuclides is increasing because of rapid industrial and population growth. The removal of these contaminants from water via ...
Anisotropy in the magnetic interaction and lattice-orbital coupling of single crystal Ni3TeO6.

Ghosh, Anirudha; Chen, K H; Qiu, X S; Hsieh, Henry; Shao, Yang (Springer, 2018-10)

This investigation reports on anisotropy in the magnetic interaction, lattice-orbital coupling and degree of phonon softening in single crystal Ni3TeO6 (NTO) using temperature- and polarization-dependent X-ray absorption ...
Organic Matrix Stabilized Ultra‐Fine Bismuth Oxide Particles for Electrochemical Energy Storage Application

Devi, Nishu; Ghosh, Sarit Kumar; Ray, Sekhar C; Mallick, Kaushik (© 2018 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim, 2018-11)

The synthesis of an organic‐inorganic supramolecular hybrid system has been reported, using a wet‐chemical synthesis method, where the Bi2O3 nanoparticles are dispersed within the organic matrix. The XRD analysis showed ...
Photoluminescence Quenching and Enhanced Optical Conductivity of P3HT-Derived Ho3+-Doped ZnO Nanostructures

Kabongo, Guy L; Mbule, Pontsho S; Mhlongo, Gugu H; Mothudi, Bakang M; Hillie, Kenneth T; Dhlamini, Mokhotjwa S (2016-09-20)

Abstract In this article, we demonstrate the surface effect and optoelectronic properties of holmium (Ho3+)-doped ZnO in P3HT polymer nanocomposite. We incorporated ZnO:Ho3+ (0.5 mol% Ho) nanostructures in ...
Numerical solution of multiband k.p model for tunneling in type-II heterostructures.

Botha, A.E. (OpenJournals Publishing, 2009-07)

A new and very general method was developed for calculating the charge and spin-resolved electron tunnelling in type-II heterojunctions. Starting from a multiband k.p description of the bulk energy-band structure, a multiband ...
