Abstract
The properties of a two-dimensional geometrically frustrated magnetic material based on the Kagomé net, , are reported. The Kagomé net is fully filled with magnetic ions. A Curie-Weiss theta is found with a spin glass transition at approximately 1.5 K, indicating strong geometrical magnetic frustration. This compound is the most two dimensional of a structural series with the geometrically frustrated materials and . The comparison of their properties tests the influence of different degrees of coupling between Kagomé layers on magnetic frustration within a single chemical and structural family.
