Biography
Marin Mirchev Gospodinov
(10.01.1944 - 14.04.2026)



Born in the Sofia vilage Dolna Sekirna

Education

He graduated from the Faculty of Physics at the Sofia University(1969)

He defended doctoral dissertation (1979) and dissertation for Doctor of Physical Sciences (1999), approved for Doctor of Physical Sciences on 04.06.2001

Research

He worked in the field of growth and study of the properties of crystals (ferroelectrics), optical properties of photorefractive crystals of oxide compounds

He created equipment and technology for crystal growth using various methods (Czochlarski's with weight control of the crystal diameter, Bridgman's, growth from a gas phase with temperature oscillation)

Over 70 new types of crystals have been created in the crystal growth laboratory (semiconductor, complex oxide crystals, ferroelectric, manganate, etc.)

A technology has been created for growing crystals for infrared light receivers from 3 to 5 microns for night surveillance with an economic effect of 850,000 leva

Crystals for uncooled nuclear radiation detectors worth $20,000 were created for the American company Targetinstruments

Prof. Marin Gospodinov headed the scientific and applied project Zikatel at the Ministry of Defense

The technological control systems created in the laboratory have been implemented in several glass factories in the country with an economic effect of 400,000 leva

Teaching experience

Prof. Marin Gospodinov lectured two courses on Condensed Matter Physics 20 semesters and Experimental Methods in Condensed Matter Physics 16 semesters at the Southwestern University in Blagoevgrad (1988-1999)

At the Southwestern University in Blagoevgrad, he supervised 8 PhD students (1973-1978)

In the crystal growth laboratory, 4 graduate students from North Korea worked under his supervision for 2 months each and 1 from Vietnam for 1 year (1985-1987)

Professional experience

BAS Institute of Solid State Physics appointed him (03.02.1970)

He was assistant (1972-1983) and associate professor in 1983

He created and headed a crystal growth laboratory (from 1983) and Materials Physics Section (from 2009)

He was head of 7 research projects funded by the Scientific Research Fund

  1. Crystal growth of high-temperature superconductors (1991)

  2. Crystal growth of complex oxide compounds (1991-1993)

  3. Photoelectric crystals growth and study (1993-1995)

  4. Growth and study of crystals with silenite structure (1996-1998)

  5. Growth and study of crystals with variable valence (2000-2002)

  6. Growth and study of multiferroic and electromagnetic crystals (2007-2011)

  7. Photorefractive crystals as media for volumetric information recording (2007)

  8. Growth and study of ferroic crystals (2007)

Prof. Marin Gospodinov was a member of the ISSP Scientific cansel (from 1983)

At the Bulgarian Academy of Sciences, he is a member of the Council on Scientific Instrumentation, the Advisory Council on Nanotechnology and the Specialized Council on Condensed Matter Physics

He was a member of the scientific council at the Institute of Mineralogy and Crystallography and of the faculty council at the Faculty of Natural Sciences and Mathematics of the Southwestern University in Blagoevgrad

He was Materials Research Society and Internationa Union of Crystalography member

He was awarded a diploma from the Bulgarian Academy of Sciences on the occasion of his 70 anniversary (2014)

He was awarded the Nikolay Semenovich Kurnikov Memorial Medal by the Institute of General and Inorganic Chemistry of the Russian Academy of Sciences. (19.11.1985)

ISSP-BAS awardet him with "Georgi Nadjakov" memorial medal

Publications
He published 233 articles and reports (171 articles and 19 reports)
