Josephson Junctions with Ferromagnetic Interlayers for Electronic Applications

Student: Kuzin Aleksey

Supervisor: Andrey Vasenko

Faculty: HSE Tikhonov Moscow Institute of Electronics and Mathematics (MIEM HSE)

Educational Programme: Infocommunication Technologies and Systems (Bachelor)

Year of Graduation: 2019

Data transmission systems operating with electronic components and integrated circuits are losing their exceptional leading position in the industry due to the rapid development of integrated optics and superconducting hybrid transitions. Superconducting devices based on the Josephson effect have unique properties that can be used in modern electronics. The goal of the research is to create and demonstrate a quantitative model describing the behavior of quasiparticle current in SFIFS junctions, depending on the ferromagnetic interlayer parameters. For this purpose, a theoretical model and basic equations were formulated, based on thematic literature. As a result, it was elaborated: a quantitative model and a family of current – voltage characteristics for SFIFS junctions. Due to the special behavior of volt-ampere characteristics, SFIFS junctions can be used as high-frequency generators.

Student Theses at HSE must be completed in accordance with the University Rules and regulations specified by each educational programme.

Summaries of all theses must be published and made freely available on the HSE website.

The full text of a thesis can be published in open access on the HSE website only if the authoring student (copyright holder) agrees, or, if the thesis was written by a team of students, if all the co-authors (copyright holders) agree. After a thesis is published on the HSE website, it obtains the status of an online publication.

Student theses are objects of copyright and their use is subject to limitations in accordance with the Russian Federation’s law on intellectual property.

In the event that a thesis is quoted or otherwise used, reference to the author’s name and the source of quotation is required.
