We propose to study the mechanism of the first-order magnetic phase transitions (FOMT) of Nd2In and Pr2In. Unlike typical first-order magnetocaloric (MC) materials that exhibit significant thermal hysteresis, these two compounds show anhysteretic FOMT with a giant magnetocaloric effect. Although both experimental and theoretical investigations on R2In (R: Nd, Pr) indicate a strong interrelation between crystal structure, electronic band structure, and magnetic sublattice, the mechanism of FOMT in R2In is yet to be understood. Recently, we have developed a unique setup at ID12 of ESRF to measure simultaneously macroscopic physical properties (magnetization, magnetostriction, magnetocaloric, resistivity) and element specific atomistic behaviour (XAS/XMCD). Using such device, we will be able to correlate both atomistic and macroscopic measurements of the FOMTs of Pr2In and Nd2In. These results will promote fundamental understanding of the FOMTs in R2In (R: rare-earth elements).
