Abstract

The magnetic penetration depth, λ(T), was measured by means of muon spin relaxation (μSR) in a 1T field for a sample of Bi₂(Sr,Ca)₃Cu₂Ox (T_c=72K), yielding a powder averaged λ(0)=3060 A ̊. The T-dependence of λ does not follow the conventional two-fluid formula above 20K, which indicates substantial disorder and flux melting effects. Together with other work, the results imply a decreasing trend for T_c with increasing carrier concentration in the BiSrCaCuO system, underscoring the importance of stoichiometry dependent electronic and crystal structure effects.
