The DC susceptibility is calculated using the critical state model in which the diamagnetism and the flux-pinning effect of superconductors are taken into account. It is shown that the saturated value of the DC susceptibility at sufficiently low temperatures, i.e., the so-called Meissner fraction, decreases with increasing DC field and/or increasing specimen size.}, pages = {375--382}, title = {DC susceptibility of type-II superconductors in field-cooled processes}, volume = {170}, year = {1990}, yomi = {マツシタ, テルオ and オタベ, エドモンド ソウジ} }
