By performing high-pressure single-crystal neutron diffraction measurements,the evolution of structure and magnetic ordering in EuFe2As2 under hydrostaticpressure were investigated. Both the tetragonal-toorthorhombic structuraltransition and the Fe spin-density-wave (SDW) transition are graduallysuppressed and become decoupled with increasing pressure. The antiferromagneticorder of the Eu sublattice is, however, robust against the applied pressure upto 24.7 kbar, without showing any change of the ordering temperature. Under thepressure of 24.7 kbar, the lattice parameters of EuFe2As2 display clearanomalies at 27(3) K, well consistent with the superconducting transitionobserved in previous high-pressure resistivity measurements. Such an anomalousthermal expansion around Tc strongly suggests the appearance of bulksuperconductivity and strong electron-lattice coupling in EuFe2As2 induced bythe hydrostatic pressure. The coexistence of long-range orderedEu-antiferromagnetism and pressure-induced superconductivity is quite rare inthe EuFe2As2-based iron pnictides.
