Abstract
Results exhibiting the influence of cold rolling fluxoid pinning in a metalic glass superconductor (Mo0.6Ru0.4)82B18 are reported. Inhomogeneous deformation up to 20% reduction in thickness does not change either the superconducting transition temperature Tc or upper critical field Hc2 but does degrade the critical current density by as much as 34% from the value in the the as‐cast condition. Possible mechanisms for this degradation of Jc are suggested. Pinning by inhomogeneities in composition or density rather than by the simple surface or unresolved second‐phase precipitates appears to be likely.Keywords
