Abstract
The spectral dimensions of spin-wave fractons in percolating antiferromagnets are investigated in terms of a dynamic scaling argument and numerical simulations. It is found, by the scaling argument, that the value of the spectral dimension [Formula: see text] of antiferromagnetic fractons should be less than unity for any Euclidean dimensions d(≥2). Simulated results of [Formula: see text] for d=2, 3 and 4 percolating antiferromagnets indicate that [Formula: see text] are very close to unity independent of Euclidean dimension d.
