Modelling higher trapped fields by pulsed field magnetisation of composite bulk MgB2 superconducting rings
2021
Superconductors Science and Technology
The recent results of Hirano et al (2020 Supercond. Sci. Technol. 33 085002) reported a high trapped field of 1.61 T in a composite MgB 2 ring comprising copper plates and and a soft iron yoke magnetised by pulsed field magnetisation (PFM). Inspired by these results, an investigation using systematic modelling methods was conducted to investigate the key parameters leading to the success of Hirano et al. Our results indicate that composite structures of MgB 2 rings present a viable method of
