Understanding the giant barocaloric effect in Mn3AN using pressure and temperature dependent inelastic neutron scattering

Abstract: Materials with large caloric effects offer the opportunity to replace current refrigeration technologies that require the compression of hazardous gases. Barocaloric materials driven using hydrostatic pressure are advantageous due to the relative ease and cost of creating mechanical pressure. Giant barocaloric effects (BCE) have recently been observed in the material Mn3GaN, however our measurements on the closely related Mn3NiN reveal yet larger effects. Our previous experiment on MERLIN revealed anomalous features that remain unexplained and may be related to the BCE. To further understand these anomalous results, we propose to (i) perform pressure dependent experiments on Mn3NiN to complement our previous results and (ii) perform temperature dependent experiments on the closely related Mn3GaN (giant BCE) and Mn3SnN (zero BCE) to provide an important comparison to Mn3NiN.
