Summary of results for frustrated magnets. (a) Heisenberg pyrochlore antiferromagnet; (b) ‘‘hexagonal
spin cluster’’ spinel ZnCr2O4; (c) GGG; (d) hyperkagome Na4Ir3O8; (e) extended kagome YBaCo4O7; (f ) kagome XY system; (g) kagome Ising system. The left-hand column shows the RMC fit to simulated powder diffraction data (calculation
details given in Ref. [12]). Input data are shown in black, RMC fit in red, and difference (RMC data) in blue.
