Abstract: The Andreev-like levels and the free energy of the spin superconductor/insulator/spin superconductor junction are obtained by using the Bogoliubov-de Gennes equation.The phase dependence of the spin supercurrents exhibits a 0-π transition by changing the barrier strength.The dependences of the critical current on the barrier strength and the temperature are also presented.
