Description
Summary:Longitudinal-field muon-spin-relaxation measurements have revealed inhomogeneous distribution of the internal magnetic field at temperatures above the bulk superconducting (SC) transition temperature, \(T_{\rm c}\), in slightly overdoped Bi\(_2\)Sr\(_2\)Ca\(_{1-x}\)Y\(_x\)Cu\(_2\)O\(_{8+\delta}\). The distribution width of the internal magnetic field, \(\Delta\), evolves continuously with decreasing temperature toward \(T_{\rm c}\). The origin of the increase in \(\Delta\) is discussed in terms of the creation of SC domains in a sample.
