Galkin Monument in Donetsk

Oleksandr Oleksandrowytsch Halkin (* July 4 ^{. Jul} / 17th July  1914 ^greg. In Berdyansk ; † 22. October 1982 in Donetsk ) was a Ukrainian state physicist and university teacher .

Life

Halkin graduated from Kharkov University in 1939.

1937–1960 Halkin worked at the Kharkov Physics and Technology Institute of the Academy of Sciences of Ukraine , interrupted from 1941–1945 due to his participation in the German-Soviet War . In 1945 he was involved in the discovery of the diode properties of superconductors . In 1955 he became a Doctor of Physical and Technical Sciences PhD . In 1957 he was involved in the discovery of the cyclotron resonance in tin and lead involved and in 1958 on the discovery of the dispersion of the sound velocity in the magnetic field , in 1959 to the discovery of oscillations of ultrasound - absorption coefficient and 1960 to the discovery of the anisotropy of the energy gap of the superconducting tin.

In 1960, together with BI Werkin , BN Eselsohn and IM Dmitrenko , Halkin initiated the establishment of the Institute for Low Temperature Physics and Technology of the Academy of Sciences of Ukraine in Kharkov, of which Galkin became the deputy director (and which now bears Werkin's name). Galkin contributed to the discovery of the Rashba effect in semiconductors in 1965 by EI Raschba at the Semiconductor Institute of the Academy of Sciences of Ukraine.

In 1965 Halkin became a member of the Academy of Sciences of Ukraine and founded the Donetsk Physics and Technology Institute of the Academy of Sciences of Ukraine, which he headed until his death. The main research areas were solid state physics , condensed matter physics , microwave spectroscopy , superconductivity and high pressure physics. At the institute, Galkin founded a school for high pressure physics and solid-state spectroscopy. In 1970 he established the thermodynamic stability of the domain structure in antiferromagnetic materials. In 1971 he discovered the irreversible induction of new ferromagnetic states by a strong magnetic field. In 1972 Galkin developed a method for unsteady hydro- extrusion . In 1977 he discovered the Doppleron- phonon - resonance in cadmium and molybdenum .

On Halkins initiative leading scientists taught the Donetsk Physics and Technology Institute in Physics - Faculty of the University of Donetsk and attracted new employees approach for the institute. Galkin himself was also a professor at Donetsk University.

In 1994 the Donetsk Physics and Technology Institute was named after Alexander Alexandrowitsch Galkin. His monument was erected in front of the institute.

Honors

• State Prize of the Ukrainian Socialist Soviet Republic (USSR) (1971) together with WG Barjachtar , SN Kowner and JP Stefanowski for the discovery as well as the experimental and theoretical investigation of the intermediate state of antiferromagnetic materials
• KD Sinelnikow Prize (1975) together with EA Sawadski for the induction of a new material state by a strong magnetic field
• State Prize of the USSR (1982) together with WP Burjak and NI Matrossow for the development and investigation of superconductors with improved properties
