One of the hallmark of superconductivity is the zero resistance state, characterised by dissipation- less current (supercurrent) that can be sustained by a superconducting body. In a conventional superconductor, the supercurrent is usually recip- rocal, i.e. the maximal amount of supercurrent can be sustained both in the forward and in the backward direction. The scientific community has make extensive efforts in recent years to create a non-reciprocal superconducting device, named a supercurrent diode, a device ideally capable of sustaining supercurrent in one direction and tran- sitioning to the normal state when trying to force a supercurrent in the opposite direction. The scope of this thesis is to achieve diode properties in a superconducting hybrid film (superconductor- semiconductor), made of a bilayer of aluminium (Al) and nickel dibromide (NiBr2). The nickel dibromide is a Van Der Waals semiconductor char- acterized by a non-coplanar spin pattern at the surface. The exchange interaction mechanism at the interface between the superconductor and the semiconductor induces magnetochiral anisotropy in the conventional superconducting Al film and so, in presence of an external magnetic field, a non-reciprocal supercurrent can be achieved.
