Fig. 1: Typical lamellar polar domain patterns observed on GaV4Se8 crystals.

a, b Frequency shift image obtained at 8.4 K on a (111) surface and at 11 K on a (001) surface, respectively. The color represents the shift in the cantilever resonance frequency, given in [Hz] units in the color bar. The contrast is not due to magnetic textures but reflects the polar domain pattern.
