Evaluation of magnetic loss in a YBa2Cu3Ox superconductor
- 1. Shinshu Univ., Faculty of Textile Science and Technology, Ueda, Nagano (Japan)
Description
We measured the magnetic force between a YBa2Cu3Ox (YBCO) superconductor and a Nd-Fe-B magnet while reciprocating the superconductor under the magnet. The magnetic force showed a hysteretic characteristic against the displacement of the superconductor. Magnetic loss calculated from the hysteresis curve decreased as the drive frequency increased. A mechanical model was used to analyze the characteristics of the magnetic loss. By adding the contribution of viscous force and repined flux lines to the mechanical model, we obtained good agreement between the analytical and experimental results. (author)
