Title of Research: Magnetocaloric Effect (MCE) 

Research Purpose: To obtain missing information and the Magnetocaloric properties of two compounds.

Aims of the research:

  • Synthesis of polycrystalline material of Mn4FeSi3 and Mn2Fe3Si3 and growth of large single crystals using the Czochralski method.
  • Oriented cutting of the crystals to prepare suitable samples for direction dependent magnetic measurements.
  • Measurement of direction dependent macroscopic magnetic properties using the Vibrating Sample Magnetometer option. The magnetic field will be applied along the three different crystallographic directions of the orthorhombic/hexagonal unit cell. Magnetization measurements will be performed using both isothermal and isofield conditions.
  • Analysis of the data and extraction of the direction dependent magnetocaloric effect.
  • Establishment of structure property relationships and comparison of the compounds to other members of the series
