Non-collinear chiral magnetic structure in rare earth nickelates

ORAL

Abstract

We resolved the debate on the non-collinear nature of the antiferromagnetic spin structure in nickelates. With the polarization resolved resonant X-ray scattering tuned to the Ni L3-edge with azimuthal rotation, we revealed the unambiguous non-collinear chiral magnetic structure with a net chiral polarization on the domains in NdNiO3. In combination with model calculations, our results allow accurate determine of the chiral magnetic structure and the population of the chiral domains that had not been observed in prior work on nickelates.
