Abstract

In the mixed state of Bi2.15Sr1.85CaCu2O8+δ the temperature dependence of the muon spin rotation (μSR) linewidth is found to have a strong field dependence, which is attributed to the effect on the line shapes resulting from thermal fluctuations of the vortex positions. This provides important information concerning the form of the fluctuations and moreover gives a measure of the anisotropy parameter γ. By combining this result with a μSR determination of the penetration depth λ(T) and the melting line Bm(T), we are further able to obtain the Lindemann number cL.
