Geometrically frustrated Kagome staircase lattice with chemical disorder

Abstract The effect of nonmagnetic Mg 2+ and magnetic Co 2+ doping in Kagome staircase compounds was investigated using DC magnetic susceptibility. The main effect of doping is to change effective anisotropy of the Ni 3 V 2 O 8 and Co 3 V 2 O 8 crystals. It has a considerable effect on magnetic field induced phase transitions in both kinds of crystals. The doping has also an effect on the Dzyaloshinskii–Moriya exchange interactions. In some cases the doping enhances this interaction while in another it suppresses it completely.
