Pinning of the domain walls of the cluster spin-glass phase in LTT La_{2-x}Ba_xCuO_4
F. Cordero, A. Paolone, R. Cantelli +1
We compare the low frequency (~1 kHz) anelastic spectra of La_{2-x}Sr_xCuO_4 and La_{2-x}Ba_xCuO_4 at x = 0.03 and 0.06 in the temperature region where the freezing into the cluste…

Observation of the cluster spin-glass phase in La_{2-x}Sr_{x}CuO_{4} by anelastic spectroscopy
F. Cordero, R. Cantelli, A. Paolone +1
An increase of the acoustic absorption is found in La_{2-x}Sr_{x}CuO_{4} (x = 0.019, 0.03 and 0.06) close to the temperatures at which freezing of the spin fluctuations in antiferr…
