Interplay between phonon and magnon excitations in the magnetocaloricFe2P based alloys.
A lot of experimental and theoretical attention has been paid to compounds that display magnetocaloric properties in an effort to reduce the worlds dependency on hazardous gasses such as hydrofluorocarbons for refrigeration. Fe2P based alloys have shown great potential for magnetocaloric devices. The aim of this work is to perform a comparative study of the low energy dynamics in the parent compound, Fe2P, and the most promising compound, FeMnP0.5Si0.5, to gain a further grasp on the role of electron-phonon interactions and magnetoelastic coupling that lead to the enhanced entropy change necessary for magneto caloric devices.
