Abstract

In this study, the magnetic field effect was investigated on the magnetic and electric properties of a chiral-polar-ordered corundum, Ni2InSbO6. Single-crystal soft x-ray and neutron diffraction measurements were used to verify the magnetic modulations with long wavelengths. The modulation direction tends to align along the magnetic field when it is applied perpendicular to the polar axis, suggesting that the nearly proper-screw-type helicoid should be formed below 77 K owing to the dominant activation of chirality-induced uniform Dzyaloshinskii-Moriya interactions despite the existence of both chirality and polarity. When a high magnetic field is applied perpendicular to the polar axis, a helix-to-canted antiferromagnetic transition is observed through the intermediate soliton lattice type state. In contrast, a magnetic field applied along the polar axis induces a first-order metamagnetic transition. These metamagnetic transitions accompany a change in the electric polarization along the polar axis.
