摘要
Powder neutron-diffraction measurements of the frustrated kagome lattice antiferromagnets Na- and K-jarosites (AFe(3)(OH)(6)(SO(4))(2): A = Na and K) were carried out. The determined magnetic structure at 10 K is the so-called q = 0 structure and found to be different from one reported previously for K-jarosite. The intensities of magnetic reflections show slow decreasing with increasing temperature near T(N) and seem to imply successive phase transitions observed ina recent NMR study.
