Antiferromagnetic Fractons Observed by Inelastic Neutron Scattering Experiments.

We present an analysis of the experimental data obtained by means of inelastic neutron scattering (INS) experiments for diluted Heisenberg antiferromagnet RbMn 0.39 Mg 0.61 F 3 (H. Ikeda et al. , J. Phys. Soc. Jpn. 67 , 3376 (1998)). Calculated results recover well INS results. These results confirm the observation of antiferromagnetic fractons in RbMn 0.39 Mg 0.61 F 3 by Ikeda et al.
