We report pressure-induced superconductivity in a single crystal of CaFe 2 As 2 . 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 T c suppression with applied magnetic field is −0.7 K T −1 , giving an extrapolated zero-temperature upper critical field of 10–14 T.
