Abstract
In order to study the “ \(\frac{1}{8}\) effect” in different high-T c oxides from the La-system, muon spin relaxation measurements were applied to the Zn-substituted Bi-2212 system, Bi 2 Sr 2 Ca 1−x Y x (Cu 1−y Zn y ) 2 O 8+δ , around the hole concentration p= \(\frac{1}{8}\) per Cu. It has been revealed that the magnetic correlation between Cu spins is anomalously enhanced in the Zn-substituted samples at \(p \sim \frac{1}{8}\) per Cu, proving the existence of the “ \(\frac{1}{8}\) effect" in the Bi-2212 system as well.
