Abstract

We studied spiral-type spin correlations in Mn_0.07Mg _0.93Cr₂O₄ by single-crystalline neutron scattering. The correlation lengths are evaluated to be 12.7 Å and 4.4 Åalong parallel and perpendicular to the propagation vector, respectively. The spiral rotational plane is estimated to be the proper-screw type rather than the cycloid-screw one. This fact suggests that Mn moments stabilize the cycloidal structure, generating the ferroelectricity in the parent material MnCr₂O₄.
