CIOMAGA HATNEAN
Scientist
I'm a Switzerland based Scientist (Chemist) working on synthesis, crystal growth and characterisation of various materials with interesting properties. My research is placed at the interface between Materials Science, Solid State Chemistry and Condensed Matter Physics.
Research Interests
-
Synthesis, crystal growth and characterisation of polycrystalline and single crystalline samples of various compounds (oxides, borides, chalcogenides, oxichalcogenide and intermetallics).
-
Study of materials that exhibit interesting structural and physical properties. These materials belong to the following areas of research:
-
Exotic states of matter (e.g. skyrmionic materials, topological insulators, superconductors, etc).
-
Frustrated magnetism (e.g. pyrochlores, garnets, Shastry-Sutherland lattices, etc).
-
Multiferroic, ferroelectric and magnetoelectric materials (e.g. ferrites, manganites, etc).
-
2D and other van der Waals materials (e.g. semiconductors, superconductors, etc).
-
Polymorphism, structural phase transitions, structural disorder and their effect on the physical properties of the material.
