Half-integer Shapiro steps at the 0-pi crossover of a ferromagnetic Josephson junction

H. Sellier, C. Baraduc, F. Lefloch +1

We investigate the current-phase relation of S/F/S junctions near the crossover between the 0 and the pi ground states. We use Nb/CuNi/Nb junctions where this crossover is driven b…
