Search for valence transitions in MgEu alloys

An experimental investigation has been performed on a series of MgEu alloys, ranging in concentration from 46 ppM to 33.84 a/o Eu, in order to study the possibility of a valence transition occurring in this system. Part of the experimental study was performed in collaboration with Dr. Gopal Shenoy of Argonne National Laboratory. In view of the importance of crystallographic and metallurgical structures in valence transitions, the study not only encompassed the magnetic and electronic characterization of this system but also the elastic, crystallographic, thermal, transport, metallurgical and phase properties as well
