Abstract:
Antiferromagnet-superconductor (AFM-SC) hybrids offer a rich but largely unexplored platform for realizing spin-triplet Cooper pairing and chiral topological superconductivity, yet experimental demonstrations remain scarce. Here, we report the modification of superconductivity in NbSe_{2}/MnPS_{3} heterostructures via the AFM proximity effect. The Néel order of MnPS_{3} effectively suppresses the Ising superconductivity of NbSe_{2} and induces a spatially inhomogeneous superconducting state with an inherent junction network. Leveraging this intrinsic Josephson coupling, we observe a finite phase offset in the critical-current interference pattern and a zero-field supercurrent diode effect-two independent signatures of spontaneous time-reversal symmetry breaking. Supported by theoretical modeling, we attribute these emergent phenomena to the proximity-induced stabilization of a subdominant in-plane triplet pairing channel, which is distinct from the intrinsic Ising channel of NbSe_{2}. Our findings establish AFM-SC heterostructures as a versatile platform for exploring nonreciprocal transport and open promising avenues for superconducting spintronics.
