Sg. Barsov et al., INVESTIGATION OF MAGNETIC ORDERED STATE IN YBA2CU3O6-LESS-THAN-X-LESS-THAN-0.32) BY MU-SR(X (0.06), Hyperfine interactions, 86(1-4), 1994, pp. 543-548
The magnetic state properties have been studied in YBa2Cu3O6+x with (0
.06< x <0.32). The increase of muon depolarization rate was found belo
w 100K in all samples. In contrast to the previous muSR-studies two pr
ecession signals with the frequencies close to 4MHz was observed at T=
20 divided-by 80K. Possible reasons of the phenomena at T<100K are dis
cussed.
