An increase of the acoustic absorption is found in La2-xSrxCuO4 (x=0.019, 0.03, and 0.06) close to the temperatures at which freezing of the spin fluctuations in antiferromagnetic-correlated clusters is expected to occur. The acoustic absorption is attributed to changes of the sizes of the quasifrozen clusters induced by the vibration stress through magnetoelastic coupling.

Abstract
An increase of the acoustic absorption is found in La2-xSrxCuO4 (x=0.019, 0.03, and 0.06) close to the temperatures at which freezing of the spin fluctuations in antiferromagnetic-correlated clusters is expected to occur. The acoustic absorption is attributed to changes of the sizes of the quasifrozen clusters induced by the vibration stress through magnetoelastic coupling.File in questo prodotto:
