“…In neutron scattering studies of these AF-LCO systems, the Bragg peak intensity I B shows a reduction, by more than a factor of 10, with decreasing T N . 28 In contrast, the frequency of ZF-SR spectra shows only a 20% change in the local frozen moment for the same reduction of T N . These SR and neutron results on AF-LCO are compared in Ref.…”

“…These SR and neutron results on AF-LCO are compared in Ref. 28. Since the SR frequency is directly proportional to the magnitude of neighboring static Cu moments, the reduction of I B in neutron studies cannot be ascribed to a change of individual Cu moment size.…”

“…Subsequently, SR studies on La 2 CuO 4 , 28 (La,Li) 2 CuO 4 , 29 La 2Ϫx Sr x CuO 4 , [30][31][32][33][34] and YBa 2 Cu 3 O y , 34,35 were performed to characterize magnetic phase diagrams as a function of hole concentration and also to study details of the spin glass states near xϭ0.05.…”

“…20 Harshman et al first identified the SG phase with SR. 21 Hitti et al 22 identified the muon site in La 2 CuO 4Ϫy by comparing neutronscattering measurements of the moment size to the SR precession frequency. As already mentioned, the lightly Srdoped region has been explored by Borsa CuO 4 systems.…”

Muon Spin Rotation in High TcSuperconductors

“…The authors claimed that TN decreases with increasing oxygen content. Such scaling was followed in the μSR works of Uemura et al [25,27]. The work of Budnick at al.…”
