Goremychkin, EA, Osborn, R, Rosenkranz, S, Lumsden, MD, Malliakas, CD, Todorov, IS, ...
A new family of superconductors containing layers of iron arsenide has attracted considerable interest because of their high transition temperatures (Tc), some of which are >50 K, and because of...
Observation of two spin gap energies in the filled skutterudite compound CeOs4Sb12 (2007)
Adroja, DT, Park, J-G, Goremychkin, EA, McEwen, KA, Takeda, N, Rainford, BD, ...
The optical conductivity of the Kondo insulator compound CeOs4Sb12 reveals the formation of a 70 meV charge gap below 160 K. It also exhibits a weak shoulderlike structure at 30 meV, below 60 K. We...
