Abstract

We study narrow ballistic Josephson weak links in an InAs quantum well contacted by Nb electrodes. Measurements of the conductance, excess and critical currents reveal a dramatic magnetic-field suppression of the Andreev reflection amplitude, which occurs even for in-plane field orientation with essentially no magnetic flux through the junction. Our observations demonstrate the presence of an ...
