TY  - JOUR
AB  - The magnetically frustrated manganese nitride antiperovskite family display significant changesof entropy under hydrostatic pressure that can be useful for the emerging field of barocaloric cool-ing. Here we show that barocaloric properties of metallic antiperovskite Mn nitrides can be tai-lored for room temperature application through quaternary alloying.We find an enhanced en-tropy change of St= 37 J K−1kg−1at theTt= 300 K antiferromagnetic transition of quater-nary Mn3Zn0.5In0.5N relative to the ternary end-members.The pressure-driven barocaloric entropychange of Mn3Zn0.5In0.5N reaches SBCE= 20 J K−1kg−1in 2.9 kbar.Our results open up a largephase space where new compounds with improved barocaloric properties may be found.
