In this talk, I will discuss our recently developed suitable topological superconducting platform that promise to host robust MZM in multilayer hetero-structures. In combination of spatial resolved tunneling spectroscopy with high spin & energy resolution and theoretical modeling, we show the interplay between superconductivity, spin-orbit coupling and Zeeman field [1-2]. This novel platform opens up the possibility for realizing MBS manipulations in stable and scalable metallic thin-film nanostructures, where strong SOC intrinsic exchange field ensures much more robust MZM compared to other analogous semiconductor-based schemes [3]. To the end I will also show how spin resolved spectroscopy provide crucial insight towards the relationship between the insulating states with a charge gap and the magnetic order in the Mott insulating states [4].
