Pressure-Induced Superconductivity in Quasi-2D CeRhIn5

CeRhIn₅ is a new heavy-electron material that crystallizes in a quasi-2D structure that can be viewed as alternating layers of CeIn₃ and RhIn₂ stacked sequentially along the tetragonal c axis. Application of hydrostatic pressure induces a first-order-like transition from an unconventional antiferromagnetic state to a superconducting state with T_c = 2.1 K.
