概要

• 論文の詳細を見る

• Magnetic fractons in the near-percolating three-dimensional (3D) Heisenberg antiferromagnet, RbMn_<0.4>Mg_<0.6>F_3, were studied using inelastic neutron scattering with a high energy resolution (ΔE=17.5 μeV) and at low temperature (T=1.5K). It was demonstrated that the fractons follow the dispersion relation of q^Z (q being the wave number). The observed exponent, Z=2.5, was in good agreement with the fractal dimension of the 3D system (D_f=2.48), as predicted by theory.
