0-π transition induced by the barrier strength in spin superconductor Josephson junctions

doi:10.1088/1674-1056/27/9/097401

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.
