pinning force density in polycrystalline Bi₁.₈Pb₀.₄Sr₂Ca₂₋ₓYₓCu₃Oy multiphase systems

ac susceptibility measurements as a function of temperature T and the ac magnetic field amplitude, Hₐc, have been performed on five superconducting Bi₁.₈Pb₀.₄Sr₂Ca₂₋ₓYₓCu₃Oₓ polycrystalline samples (x = 0, 0.005, 0.04, 0.15 and 0.36, and with the volume fraction of the Bi₂Sr₂Ca₂Cu₃Oy (2223) phase, f...
