Heavy fermion superconductivity in the filled skutterudite compound PrOs${}_4$Sb${}_{12}$

Abstract

The filled skutterudite compound \PrOsSb{} has been found to exhibit superconductivity with a critical temperature $T_{\mathrm{c}}=1.85$ K that develops out of a heavy Fermi liquid with an effective mass $m^{\ast }\approx 50m_{\mathrm{e}}$. The current experimental situation regarding the heavy fermion state, the superconducting state, and a high field, low temperature phase that is apparently associated with magnetic or quadrupolar order in \PrOsSb{} is briefly reviewed herein.
