Ce-Based Heavy-Fermion Superconductors

Abstract

Cerium-based heavy-fermion superconductors are one class of unconventional superconductors. Most of the members exhibit superconductivity in the vicinity of a quantum critical point which is often reached only under hydrostatic pressure. In the following sections only those Cerium compounds are reviewed where superconductivity appears already at ambient pressure. In those compounds the superconducting state has been investigated and characterized by many different probes which results in a detailed knowledge of the superconducting properties.
