Abstract

We have discovered fish-tail phenomenon / peak effect in a (Hg,Pb)(Ba,Sr) 2 Ca 2 Cu 3 O 8+δ [(Hg,Pb)(Ba,Sr)-1223] single crystal. Microscopic analyses and observations were performed to elucidate the origin of peak effect in terms of the micro-structure of the (Hg,Pb)(Ba,Sr)-1223 single crystal. In a [001] ED pattern of the crystal, streaks were observed along <110> at each spot. Distortions were seen along <110> in HRTE-micrograph of the (001) plane, and a compositional modulation was clearly detected with respect to the Hg/Pb ratio along [110] with an average periodicity of ∼18 nm. Such a spinodal-wave-like inhomogeneity in the local composition may yield mesoscopically distributed weak pinning centers which is most likely responsible for the appearance of peak effect.
