Determining the nuclear and magnetic structures of multi-component manganese antiperovskite nitride alloys
Materials with large caloric effects offer the opportunity to replace current cooling technologies that require the compression of hazardous gases. Whilst magnetocaloric materials driven using magnetic fields are currently the most developed for applications, there is growing interest in barocaloric materials driven using hydrostatic pressure. Our recent studies on the Mn antiperovskites Mn3(A,B)N have revealed giant barocaloric effects with minimal thermal hysteresis at first-order paramagnetic to antiferromagnetic transitions. Alloying on the (A,B) site facilitates the tuning of the transition for room temperature applications whilst maintaining the giant barocaloric response. Inspired by the field of high-entropy alloys, we have now begun to investigate multi-component systems with >3 elements on a single crystallographic site. For Mn3(Cu,Ga,Ni,Zn)N and Mn3(Cu,Ga,Sn,Zn)N we find the magnetic transition remains strongly 1st-order yet the hysteresis is again negligible. Here we propose to use D20 to determine the magnetic structure of these compounds as a function of temperature. Ultimately, the results will guide future exploration of these flexible and functional material family
