Abstract

A narrow intragrain phase-lock transition was observed in (formula presented) under a magnetic field H up to a few Tesla. The corresponding transition temperature (formula presented) decreases rapidly (formula presented) at low fields) with H, indicating that the grains of (formula presented) behave unlike a homogeneous bulk superconductor. Our data suggest that the bulk superconducting transition may occur on a length scale well below the grain size (formula presented).
