摘要：

A series of quasielastic and inelastic neutron scattering experiments have been performed in the diluted insulating antiferromagnets, Rb2Mn cMg1-cF4, Rb2CocMg 1-cF4, MncZn1-cF2 and KMncZn1-cF4. The concentrations c were chosen so as to span the percolation threshold value c=cp; for c<c p no long range order is observed. We describe briefly the results of these experiments with special emphasis on the development of the magnetic correlations at low temperatures for samples with c?cp.
