## Description

- description: Planar graphene-NbSe2 Josephson junctions can support supercurrents
    at high in-plane magnetic fields (B∥) due to the robust superconductivity in thin
    NbSe2, protected from both orbital and spin- driven decay by a combination of
    atomic thickness and Ising spin orbit coupling. We fabricate and characterize
    a clean, flat graphene-NbSe2 junction encapsulated in hBN. The junction is ballistic,
    exhibiting Fabry-Perot oscillations of the critical current, and supports very
    high critical current densities. The junction is remarkably robust to both in-plane
    and out-of-plane magnetic fields, and exhibits a clear ballistic Josephson effect
    up to the maximally available in-plane field of 8T. We model the suppression of
    the critical current using a tight-binding model, accounting for the large overlap
    area between the NbSe2 and graphene. We find that the suppression is governed
    by both the Zeeman splitting of Andreev bound states and by the flux threading
    the van-der-Waals gap that separates graphene from the NbSe2 leads.
