Pressure-induced superconductivity in quasi-2D CeRhIn5

Phys Rev Lett. 2000 May 22;84(21):4986-9. doi: 10.1103/PhysRevLett.84.4986.


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.
