Abstract

We study the temperature T dependence of the Josephson critical current Ic by taking account of magnetic scattering in a superconductor/ferromagnet/superconductor junction. When the ferromagnetic transition temperature is comparable to the superconducting transition temperature, the 0-π transition occurs by changing T due to magnetic scattering in the FM. This result is qualitatively consistent with experimental results.
