摘要：
We report systematic measurements of spin wave excitations in a well-characterized antiferromagnetic-based re-entrant spin glass system FexMn1-xTiO3. For the re-entrant spin glass sample, with x-0.60, no softening was observed. The nature of excitation spectra is controlled by the degree of disorder through the geometrical correlation length.
