Cover Story: Magnetism in Electronically Imbalanced Clathrate-like Compounds
The transition metals Fe, Co, and Ni substitute Cu in a clathrate-like compound Eu7Cu44As23 to modify its magnetic properties while keeping its crystal symmetry intact. Unlike typical clathrates, Eu7Cu44As23 is an electronically imbalanced compound allowing a wide range of heterovalent substitutions. Spins of the Eu2+ (4f7) cations that reside in oversized cages of the framework tend to order ferromagnetically; however, Ni-substituted compound shows an increase in TC to 25 K, whereas substitution of Fe for Cu suppresses ordering.
