The charge and spin freezing phenomena in high T-c YBa2Cu3O6+x superconductor is investigated in the low doping region (0 < x < 0.4) by the zero-field muon spin relaxation (ZF-muSR) technique. For x > 0.2, the observed spin freezing is correlated to the charge freezing of the holes in the Cu(2)O-2 planes. The data may be fitted to a model of size-dependent reduction of the staggered magnetization implied in a stripe scenario.

Abstract
The charge and spin freezing phenomena in high T-c YBa2Cu3O6+x superconductor is investigated in the low doping region (0 < x < 0.4) by the zero-field muon spin relaxation (ZF-muSR) technique. For x > 0.2, the observed spin freezing is correlated to the charge freezing of the holes in the Cu(2)O-2 planes. The data may be fitted to a model of size-dependent reduction of the staggered magnetization implied in a stripe scenario. The hole concentration dependence of these freezing phenomena is mapped onto the phase diagram of YBa2Cu3O6+x.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
