Abstract

High-pressure electrical resistivity measurements up to 3.0 GPa have been performed on EuFe2As2 single crystals with residual resistivity ratios RRR= 7 and 15. At ambient pressure, a magnetic /structural transition related to FeAs-layers is observed at T0 190K and 194 K for samples with RRR= 7 and 15, respectively. Application of hydrostatic pressure suppresses T0, and then induces similar superconducting behavior in the samples with different RRR values. However, the critical pressure ∼2.7 GPa, where T0 → 0, for the samples with RRR= 15 is slightly but distinctly larger than ∼2.5 GPa for the samples with RRR = 7.
