The magnetic structure of L10 ordered MnPt at room temperature determined using polarized neutron diffraction

Neutron scattering studies have been carried out on single crystal films of [001] orientated L10 ordered MnPt grown epitaxially onMgO(001) usingDCmagnetron sputtering. Polarized neutron diffraction studies at room temperature show that the moments in ordered MnPt are aligned perpendicular to the [001] axis with a tilt of 45° to the [100] axis and not parallel to [100] as inferred from previous powder neutron diffraction measurements.
