Abstract

Highlights: [•] An enhancement of J c was observed in MgB2 samples containing CNTs prepared with fine Mg powders. [•] The so-called fishtail effect was observed in both sets of CNT-containing polycrystalline samples. [•] We fitted the data to each sample by the model used in (RE)BCO system.
