Semiconducting nanowire Josephson junctions represent
an attractive
platform to investigate the anomalous Josephson effect and detect
topological superconductivity. However, an external magnetic field
generally suppresses the supercurrent through hybrid nanowire junctions
and significantly limits the field range in which the supercurrent
phenomena can be studied. In this work, we investigate the impact
of the length of InSb-Al nanowire Josephson junctions on the supercurrent
resilience against magnetic fields. We find that the critical parallel
field of the supercurrent can be considerably enhanced by reducing
the junction length. Particularly, in 30 nm long junctions supercurrent
can persist up to 1.3 T parallel field—approaching the critical
field of the superconducting film. Furthermore, we embed such short
junctions into a superconducting loop and obtain the supercurrent
interference at a parallel field of 1 T. Our findings are highly relevant
for multiple experiments on hybrid nanowires requiring a magnetic-field-resilient
supercurrent.
