【摘要】 本文用平均场理论讨论了在无限长圆柱体内有均匀分布的、方向平行于圆柱体轴线的磁短时,存在超导一铁磁性共存的条件,其中超导序参量和磁矩都不为零.结果表明,无论居里温度高于还是低于超导转变温发,这种共存相都有可能存在.更多还原

【Abstract】 According to a mean field theory,the conditions of coexistence of superco-nductivity and ferromagnetism in a long superconducting cylinder which contai-ning an uniform distribution of magnetic moment are considered.We find thatthe coexistence is possible.whether the Curie temperature is higher or lowerthan that for the superconducting transition,provided some relations betweenthe parameters are satisfied.更多还原
