高压电阻率测量高达3.0 GPa已进行EuFe_2As_2单晶与剩余电阻率比RRR= 7和15。在环境压力下，磁性/结构转变相关的FeAs层观察到在T0 = 190 K和194 K的样品与RRR= 7和15，分别。流体静压的施加抑制了T0，然后在具有不同RRR值的样品中诱导类似的超导行为。然而，对于RRR= 15的样品，临界压力约为2.7 GPa，其中T0 → 0，略微但明显大于RRR = 7的样品的约2.5 GPa。
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.
