## Abstract We try to explain how some magnets belonging to the Heisenberg universality class can be characterised by positive sound attenuation exponents near the critical point. In magnets being also insulators the sound attenuation exponent should be equal to 2__Ξ±__ where __Ξ±__ is the usual spec
In order to investigate the deviation of the spherical particle model from practical granular media in nature, the sound attenuation in a kind of water-saturated riverbed coarse sand was measured in the high frequency range \(40-600 \mathrm{kHz}\). The results reveal that the rough surface and non-s
