- 論文の詳細を見る
The change of the superconducting order parameter due to the formation of the singlet ground state in the s-d system is investigated at T=0°K. It is shown that the change of the order parameter tends to zero as |J|→∞ (J being the strength of the exchange interaction), and that the order parameter becomes zero at a certain value of |J|. The value of the thermodynamic critical field is also calculated by using the expression of the order parameter at 0°K.
