Annotation

The trapped magnetic flux in the finely ground pyrolytic graphite sample annealed at 670 K in air has been observed. Flux trapping occurs on cooling of the sample from room temperature to 10 K in a magnetic field of 1 T. The magnitude and sign of the induced trapped moment remain unchanged when the applied mag- neticfieldisvariedwithin?1TatT =10K.Thetrappedmagneticfluxismanifestedinthedisplacementof the magnetization curve relative to that of the sample cooled in zero field. Displacement magnitude gradually decreases with the temperature increase up to 350 K, not reaching zero. The set of experimental observations probably reflects the presence in the sample of a granular high-temperature superconducting phase.

Keywords

Trapped magnetic flux, pyrolytic graphite, high-temperature superconducting phase.
