Abstract
An antiferromagnet on a Kagome lattice is a strongly frustrated spin s ystem. In hexagonal compounds RFe(3)(OH)(6)(SO4)(2) [R=NH4, Na], Fe3ions form the Kagome lattice in the c-plane with the antiferromagnetic interaction. Successive phase transitions were found around 60 K by m eans of susceptibility and NMR measurements. The temperature range of the intermediate phase is about 5 K. NMR spectra of H-1 and Na-23 have structures and give information about the magnetic structures in each phase.
