We have studied a material that has, according to our density functional theory based energy mapping, a kagome lattice with a very interesting distortion. Classical calculations arrive at a phase diagram which contains, besides three ordered phases, a large classical spin liquid phase. The material Y-kapellasite which motivated the study and led to the discovery of this phase diagram is situated in a non-collinar coplanar ordered phase, in agreement with experiment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; We are interested in modern problems of solid state theory and computational materials science.
