Abstract

The magnetic structure of the Eu2+ moments in the superconducting EuFe2(As1-xPx)2 sample with x=0.19 has been determined using neutron scattering. We conclude that the Eu2+ moments are aligned along the c direction below TC=19.0(1) K with an ordered moment of 6.6(2) μB in the superconducting state. An impurity phase similar to the underdoped phase exists within the bulk sample which orders antiferromagnetically below TN=17.0(2) K. We found no indication of iron magnetic order, nor any incommensurate magnetic order of the Eu2+ moments in the sample.
