XMCD study of a novel ferromagnetic compound Pr2Pt2In

The compound Pr2Pt2In crystallizes with the tetragonal Mo2FeB2-type structure and orders ferromagnetically below TC = 9 K. The phase transition bears a 2nd order character, and the compound belongs to a 3D-Ising universality class. Its uniqe property is enhanced magnetocaloric effect. The aim of this proposal is to investigate the microscopic magnetic properties of Pr2Pt2In using the element specificity of XMCD. We intend to study the magnetism of the Pr ion at the Pr L3,2-edges (2p → 5d and 2p → 4f transitions), as well as to search for magnetism induced at the Pt atom site via the f-d hybridization and possibly observable at the Pt L3,2-edges.
