摘要：

We report pressure-induced superconductivity in a single crystal of CaFe2As2. At atmospheric pressure, this material is antiferromagnetic below 170 K but under an applied pressure of 0.69 GPa becomes superconducting, with a transition temperature T-c exceeding 10 K. The rate of Tc suppression with applied magnetic field is - 0.7 K T-1, giving an extrapolated zero-temperature upper critical field of 10 - 14 T.
