Structural and low-field magnetic characterization of superconducting MgB2 wires. Physica C: Superconductivity and its Applications, 415(1-2), 51-56. doi:10.1016/j.physc.2004.07.017 | Abstract: | Superconducting MgB2 composite wires were prepared by packing blend of MgB2 inside of Cu tubes using powder in tube (PIT) method. The produced samples of the wires were then characterised by using SEM, XRD and AC susceptibility measurements, The measured fundamental susceptibility is compared with Bean model. We have obtained an empirical functions for the penetration field Hp = Hα(1-t)β, where t is the reduced temperature. In addition, ac losses were calculated at the same fixed temperatures to compare theoretical solutions. There is a qualitative agreement between the experimental results and theory. | URI: | http://doi.org/10.1016/j.physc.2004.07.017 http://hdl.handle.net/11147/4732 |
