Abstract

Polycrystalline Hg_1-xBi_xBa₂Ca₂Cu₃O _y materials, with Bi-content x = 0.1,0.2 and 0.3, were prepared by a direct, one-step synthesis. Characterization methods included X-ray diffraction, SEM, and studies of the magnetization M. The T_c's were 133.5, 133 and 128 K, respectively. The persistent current density Jp falls off roughly exponentially with field H and temperature T. The irreversibility fields H_irr(T) ∼ (1 - T/T_c)ⁿ, with n ≈ 3, were similar for the three materials. Analysis of the equilibrium M with London theory provided the London penetration depth λ(T).
