Professor Alexandre Sigov has attained a worldwide reputation as a prominent expert in Solid State Physics and Solid State Electronics and as an active member of the international ferroelectric community. During the course of his scientific career he contributed extensively to the phenomenology of magnets, ferroelectrics and multiferroics, physics of ferroic-based heterostructures and films, etc. The results of his scientific activity are reflected in more than 300 publications and 5 monographs. Additionally, he is a co-inventor of about 40 inventions. He created his own school and inspiring and mentoring many talented scientists. In 2011 Alexandre Sigov was elected as a Member of the Russian Academy of Sciences.
Alexandre Sergeevich Sigov was born on May 31, 1945. In 1968 he was graduated with distinction from Moscow Lomonosov University. His diploma work and Ph.D. Thesis in the Moscow University, prepared under the supervision of the famous Prof. L.V. Keldysh, were related to semiconducting and magnetic systems, particularly to cross-linked magnetic domain walls.
In 1972 he entered the Moscow State Institute of Radio Engineering, Electronics and Automation (MIREA), where he rose from a lecturer to President and where he continues to work up to now. Simultaneous with the teaching activity he was doing ongoing scientific investigations in magnetic systems. The logical development of these studies was his entry to ferroelectricity. At that times Alexandre Sigov together with Arkadii Levanyuk focussed on the contribution of point defects in ferroelectric and magnetic crystals and non-ideal superconductors. The results of these studies were reflected in the Sigov's doctoral thesis on the impact of defects on crystal properties in the vicinity of structural and magnetic phase transitions and later summarized in the world-known monograph “Defects and Structural Phase Transition” (1987) by A.P. Levanyuk and A.S. Sigov.
Alexandre Sigov is always open to new ideas and mainstreams in his scientific field. In MIREA, he started wide fundamental and applied research in ferroelectric films and heterostructures, aimed at applications in micro- and nanoelectronics. Along with this application- oriented activity, he continues his fundamental investigations in ferroics. A series of theoretical works on thin-filmed magnetic materials, such as multi-layer systems ferroelectric-ferromagnetic, ferromagnetic-paramagnetic, etc is developed.
Prof. Sigov is a well-known organizer of scientific conferences. He is the head of the Russian Academy Council on Ferroelectricity, member of numerous scientific societies (European Physical Society, American IEEE, European and International Steering Committee of Ferroelectric Conferences and the Associate Editor of Ferroelectrics and Integrated Ferroelectrics.
The international and particularly the Russian ferroelectric community enjoys Sasha Sigov as a colleague and friend. He combines talent of a scientist and organizer. He is a good and devoted friend, a very kind, benevolent and modest person despite his distinguished position.
The list of scientific achievements does not convey the personal charm of Sasha's character. He is a deeply intellectual person, and makes great company in discussing both science and arts and literature. He is an expert in Russian poetry and a member of the Moscow Society of Bibliophiles. He is a loving husband, father and grandfather.
On behalf of his colleagues and admirers, we salute Sasha and wish him health, a long fruitful activity, new productive ideas and successful international collaboration.
