Abstract
In this study, we conducted a zero-field muon spin experiment on slightly doped La2−xSrxCuO4 from 200 K down to near the spin glass temperature (TSG). Utilizing pulsed muon beams with longer time spectra, we investigated the interplay between dynamic and static fields, which influenced the lineshapes of the nuclear dipole field. Our results reveal the emergence and growth of a Lorentzian field associated with localized moments, coexisting with nuclear Gaussian field anisotropy, as the temperature approaches TSG. This behavior of the internal fields may serve as a precursor to the spin glass state. The findings are consistent with a theoretical model that describes the electric field gradient required to characterize the spin glass state.
