Abstract
The magnetic properties of YBa2(Cu0.96Zn0.04)3Ox were studied in detai l by means of muon spin rotation and relaxation for 6.0 less-than-or-e qual-to x less-than-or-equal-to 6.92. The complete magnetic phase diag ram was mapped out and a disordered magnetic state was found to persis t between x = 6.4 and x congruent-to 6.7 (metallic transition), in con trast with pure YBa2Cu3Ox. The appearence of this magnetic state is at tributed to the effect of Zn on the doped hole dynamics and might be a ssociated with the freezing of local moments due to Zn (6.43 less-than -or-equal-to x less-than-or-equal-to 6.88), which were also detected h ere, in the paramagnetic state.
