Abstract

A narrow intragrain phase-lock transition was observed in RuSr₂EuCu₂O₈ under a magnetic field H up to a few Tesla. The corresponding transition temperature T₂ decreases rapidly (≈100 K/T at low fields) with H, indicating that the grains of RuSr₂EuCu₂O₈ 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 2-6 μm.
