The group focuses on fabrication of thin-film nanostructures and development of electronic components based on superconducting and ferromagnetic films for different prospective applications: in transmission electron microscopy, magnetic microscopy, biomagnetic applications, geomagnetic surveys, etc. The main objective is nanofabrication and study of the novel Josephson junctions, nanoSQUIDs and multilayer heterostructures on the scale of superconducting coherence length that is about 15nm for Nb thin films at 4.2 K. We use the original high oxygen pressure magnetron sputtering technology and up-to-date electron beam lithography with reactive ion etching methods for preparation of the high-Tc and low-Tc superconducting structures.

Topics:

Nanofabrication of superconducting circuits

Oxide heterostructures

Novel Josephson junctions

Superconducting quantum interferometers (SQUIDs)
