Here, we report on the structural, magnetic and superconducting properties of single and double atomic layer Mn films on a Nb(110) substrate, studied by low-temperature spin-polarized STM and STS [5]. The Mn films grow pseudomorphically on the Nb surface and host a c(2x2) antiferromagnetic ground state. First principles DFT calculations confirm the observed magnetic ground state, which is understood as the consequence of a strong nearest-neighbor antiferromagnetic exchange coupling. High-resolution STS measurements reveal proximity-induced superconductivity in the Mn thin films and the presence of in-gap states, indicating the formation of YSR bands.
