Research Areas & Excellence

The condensed matter physics and materials research is the major research focus of our Material Growth and Measurement Laboratory (MGML). More specifi cally it is magnetism, magnetocaloric phenomena, multiferroicity, superconductivity, spintronics, and research of Dirac materials.

MGML is holding an official license for onsite manipulation of U and Th metals and compounds for purposes of condensed matter and materials research. This makes MGML one of the few laboratories having a possibility of growth and measurements of novel materials containing these elements.

The main strategic objective of MGML is the excellence of the infrastructure on the international scale. MGML provides the broad scientific community unique possibilities for comprehensive experimental investigation of Condensed Matter Physic and Materials R&D.

- The MGML offers access to:

i) broad range of top-class instrument suite for metals purification, novel materials synthesis and high-quality single-crystal growth finalized by structure and composition characterization

ii) large portfolio of physical characterization techniques focusing on measurements of material properties (thermodynamic, cohesive, magnetic, electrical and thermal transport, spectroscopic, etc.) as a function of a wide range of external

conditions (temperature, magnetic fi eld – up to 19.5 T, electric field, hydrostatic pressure, uniaxial stress)
