Abstract

We introduce Nd3Sb3Mg2O14 with ideal kagome lattices of neodymium ions in ABC stacking. Thermodynamic measurements show a Curie-Weiss temperature of ΘCW=-0.12 K, a Nd3+ spin-12 Kramers doublet ground state, and a second-order phase transition at TN=0.56(2) K. Neutron scattering reveals noncoplanar scalar chiral k=0 magnetic order with a correlation length exceeding 400Å=55a and an ordered moment of 1.79(5)μB. This order includes a canted ferromagnetic component perpendicular to the kagome planes favored by Dzyaloshinskii-Moriya interactions.
