Abstract
CeIrIn{sub 5} is a member of a new family of heavy-fermion compounds and has a Sommerfeld specific-heat coefficient of 720 mJ/mol K{sup 2}. It exhibits a bulk, thermodynamic transition to a superconducting state at T{sub c} = 0.40 K, below which the specific heat decreases as T{sup 2} to a small residual T-linear value. Surprisingly, the electrical resistivity drops below instrumental resolution at a much higher temperature T{sub 0} = 1.2 K. These behaviors are highly reproducible and field-dependent studies indicate that T{sub 0} and T{sub c} arise from the same underlying electronic structure. The layered crystal structure of CeIrIn{sub 5} suggests a possible analogy to the cuprates in which spin/charge pair correlations develop well above T{sub c}. (orig.)
