| 内容記述 | The AC-current loss in a quench melt growth (QMG)-processed Y-123 bulk superconductor was found to fit well with the Norris’s formula for a superconductor with an ellipsoidal cross-section based on the Bean’s model, in spite of a rectangular cross-section and the magnetic field dependence of critical current density. The reason for this coincidence is generally argued by a theoretical analysis with respect to the effects of the magnetic field dependence of Jc, the geometry of effect of superconductor and the effect of n-value on the AC loss. In this paper, finite element method is used for the numerical analysis of the AC-current loss of the QMG bulk sample with taking into account of the latter two effects. It is found that when the aspect ratio of rectangular superconductor increases, the loss becomes small. The AC loss takes on a larger value when the n-value decreases, suggesting a large effect of flux creep. | |||||||||||||
