      abstract     = {We have studied a EuFe2As2 single crystal by neutron
                      diffraction under magnetic fields up to 3.5 T and
                      temperatures down to 2 K. A field-induced spin reorientation
                      is observed in the presence of a magnetic field along both
                      the a and c axes, respectively. Above critical field, the
                      ground-state antiferromagnetic configuration of Eu2+ moments
                      transforms into a ferromagnetic structure with moments along
                      the applied field direction. The magnetic phase diagram for
                      Eu magnetic sublattice in EuFe2As2 is presented. A
                      considerable strain (similar to $0.9\%)$ is induced by the
                      magnetic field caused by the realignment of the twinning
                      structure. Furthermore, the realignment of the twinning
                      structure is found to be reversible with the rebound of
                      magnetic field, which suggested the existence of magnetic
                      shape-memory effect. The Eu moment ordering exhibits close
                      relationship with the twinning structure. We argue that the
                      Zeeman energy in combined with magnetic anisotropy energy is
                      responsible for the observed spin-lattice coupling.},
