Crystal structure and magnetic interactions of CdK. a Kagomé layers comprising Cu2+ and Cd2+ ions possess good two dimensionality and are separated by nonmagnetic nitrate ions and crystalline water molecules. b Regular kagomé lattice composed of spin-1/2 Cu2+ ions with a Cd ion in the center of each hexagon. Magnetic interactions between spins are nearest-neighbor J, a Dzyaloshinskii–Moriya (DM) interaction as large as 10% of J, small next-nearest-neighbor interaction J2, and diagonal interaction Jd across the Cd ion in the hexagon
