English abstract:
Three series of mono-core MgB 2 wires with Nb sheath embedded in Cu subjected to different heat treatments (600 ∘C/300 min, 650 ∘C/30 min and 700 ∘C/30 min) were produced. For each series, three samples with different starting powder mixtures Mg + B (IS), MgH 2 + B (MH) and Mg + B ball milled (ML) were prepared. Hysteresis loops and magnetic relaxations were measured to calculate critical current density (via Beanīs critical state model) and mean effective activation energy (via Andersonīs flux creep theory). Thus, the highest current densities were obtained for IS and the worst superconducting properties were found for MH wires.
