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.","subitem_description_type":"Abstract"}]},"item_21_description_60":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal
