Abstract

YBa2Cu3O7–8 superconducting powders are generated by an aerosol route and classified into different size intervals in a cascade impactor. Two length scales (penetration depth, λ, and coherence length, ζ) characterizing superconductivity in aerosol‐produced superconducting grains are established for the first time from magnetization measurements. Representing the aerosol size distribution by a lognormal function, the susceptibility (χ) versus particle diameter (dp) relation is analyzed to obtain the penetration depth (λ). The lower and upper critical field strengths, Hc1 and c2, are established for the samples. Intraparticle critical current densities are computed from the magnetization results for these aerosol‐processed powders.
