abstract = {EuFe2As2-based iron pnictides are quite interesting
compounds, due to the two magnetic sublattices in them and
the tunability to superconductors by chemical doping or
application of external pressure. The effects of hydrostatic
pressure on the static magnetism in Eu(Fe0.925Co0.075)2As2
are investigated by complementary electrical resistivity, ac
magnetic susceptibility and single-crystal neutron
diffraction measurements. A specific pressure-temperature
(P-T) phase diagram of Eu(Fe0.925Co0.075)2As2 is
established. The structural phase transition, as well as the
spin-density-wave order of Fe sublattice, is suppressed
gradually with increasing pressure and disappears completely
above 2.0 GPa. In contrast, the magnetic order of Eu
sublattice persists over the whole investigated pressure
range up to 14 GPa, yet displaying a non-monotonic
variation with pressure. With the increase of the
hydrostatic pressure, the magnetic state of Eu evolves from
the canted antiferromagnetic structure in the ground state,
via a pure ferromagnetic structure under the intermediate
pressure, finally to an “unconfirmed” antiferromagnetic
structure under the high pressure. The strong ferromagnetism
of Eu coexists with the pressure-induced superconductivity
around 2 GPa. Comparisons between the P-T phase diagrams
of Eu(Fe0.925Co0.075)2As2 and the parent compound EuFe2As2
were also made.},
