New technologies based on solid state caloric effects, such as magnetocaloric, barocaloric, elastocaloric and electrocaloric effect, promise considerable efficiency gains as compared to today’s vapor compression technology. Within our research we aim for a better understanding of the relation between the material structure and dynamics to guide a sustainable material design.In caloric materials, applied fields (e.g. magnetic, electric, pressure, strain) lead to changes in entropy and in the adiabatic temperature. The observed caloric effects form the basis of the caloric refrigeration cycles. We are interested in the fundamental mechanisms of these caloric effects, which are not yet fully understood. In particular, we studied the magnetocaloric effect in the family of compounds Mn5-xFexSi3.Neutron scattering experiments were crucial for the elucidation of the magnetic and crystalline structures and for the distinction of Mn and Fe [1]. In addition, inelastic neutron scattering investigations revealed that the application of a magnetic field induces (suppresses) fluctuations in the materials. These fluctuations are closely related to the inverse (direct) magnetocaloric effect observed in these compounds [2].[1] N. Maraytta et al., J. Appl. Phys. 128, 103903, 2020 ; A. Eich et al., Mater.
