We have measured the a.c. magnetic permeability response function μ = μ′ + iμ″ in melt-processed melt-grown YBa2Cu3O7 with Y2BaCuO5 inclusions (MPMG) and in single crystal YBa2Cu3O7 (SC) in magnetic fields of up to 8 T oriented either parallel

We have measured the ac magnetic permeability response function μ = μ' + iμ'' in melt-processed melt grown YBa2Cu3O7 with Y2BaCuO5 inclusions (MPMG) and in single crystal YBa2Cu3O7 (SC) in applied magnetic fields up to 8 Tesla oriented either para

Recent work has shown that the melt-powder-melt-grown (MPMG) high temperature superconductor YBa2Cu3O7 with Y2BaCuO5 inclusions sustains unusually high critical current in the bulk. In the present paper the magnetic irreversibility line of this mater

Extensive ac-magnetic-permeability studies have been carried out on the irreversible behavior and flux dynamics in superconducting ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$ crystals in external magnetic fields up to 7.5 T. From the an

Most applications of superconducting materials require high critical current density. Melt-powder-melt-grown (MPMG) YBa2Cu3O7 with Y2BaCuO5 inclusions were found to have the highest critical current in bulk to date. The authors report a systematic st

We have measured the ac magnetic permeability μ in YBa2Cu3O7 with Y2BaCuO5 inclusions and in single crystal YBa2Cu3O7, in applied magnetic fields parallel and perpendicular to the c-axis. We find that the inclusions act as strong pinning sites when

A systematic study of the magnetic irreversibility behavior in the MPMG (melt-powder-melt-grown) material with Y 2 BaCuO 5 inclusions have been performed. The irreversibility line was measured in external fields up to 8 T using an ac susceptibility t

The irreversibility behaviour of superconducting YBa2Cu3O7 crystal in external magnetic fields is studied by ac magnetic permeability. A flux creep model with a single-relaxator form is used in the analysis. The irreversibility line B*(T*) is found t

By measurement of the ac permeability of ceramic YBCO we determine a line in the B-T plabe separating regions of flux expulsion from those of large penetration. The line intersects the temperature axis below T c and does not scale with the sample rad
