FePS3/NbS2: A candidate for topological superconductivity

Topological superconductivity is considered to be a key aspect for the development of topological quantum computing due to its potential for building Majorana-based qubits. As other exotic quantum phases, this state is not found in naturally occurring compounds. However, the progress in the research on low dimensional materials has allowed the engineering of materials with these exotic phases. One path to achieve the topological superconductivity is the engineering of heterostructures with stacking layers of 2D magnets and superconductors. Here we propose to investigate FePS3/NbS2, a heterostructure with a layered van der Walls antiferromagnet (FePS3) on a superconductor transition metal dichalcogenide substrate (NbS2). This heterostructure is a candidate for topological superconductivity. We intent to investigate the magnetic ordering, and the magnetic phase transitions. The magnetic properties will be studied by X-ray absorption (XAS), natural and magnetic linear dichroism (XNLD and XMLD) and magnetic circular dichroism (XMCD).
