Direct Observation of a Temperature Dependent 0-pi Junction Transition in a Mesoscopic High Critical Temperature Grain Boundary Junction

G. Testa, A. Monaco, E. Esposito +5

We have observed, for the first time, a temperature dependent 0-pi junction crossover in a 45 symmetric [001] tilt grain boundary junction. Experimental data, obtained by a double…
