  We report an unexpected magnetic-field-driven magnetic structure in the
5f-electron Shastry- Sutherland system U2Pd2In. This phase develops at low
temperatures from a noncollinear antiferromagnetic ground state above the
critical field of 25.8 T applied along the a-axis. All U moments have a net
magnetic moment in the direction of the applied field, described by a
ferromagnetic propagation vector qF = (0 0 0) and an antiferromagnetic
component described by a propagation vector qAF = (0 0.30 1/2 ) due to a
modulation in the direction perpendicular to the applied field. We conclude
that this surprising noncollinear magnetic structure is due to a competition
between the single-ion anisotropy trying to keep moments, similar to the ground
state, along the [110]-type directions, Dzyaloshinskii-Moryia interaction
forcing them to be perpendicular to each other and application of the external
magnetic field attempting to align them along the field direction.
