抄録
We report the ac magnetic susceptibility χac and resistivity ρ measurements of EuFe2As2 under high pressure P. By observing nearly 100% superconducting shielding and zero resistivity at P=28 kbar, we establish that P-induced superconductivity occurs at Tc∼30 K in EuFe2As2. ρ shows an anomalous nearly linear temperature dependence from room temperature down to Tc at the same P. χac indicates that an antiferromagnetic order of Eu2+ moments with TN∼20 K persists in the superconducting phase. The temperature dependence of the upper critical field is also determined.
