Magneto-Chiral Sensors for Hydrogen Leakage Detection Using Heavy Metal Complex Coatings on Fe Co/Si system: A Potential New Approach

The magnetic properties of Wilkinson Catalyst/Fe-Co/Si as a function of Wilkinson catalyst concentration in solution were first time measured using polar magneto-optical Kerr effect (PMOKE) magnetometry. PMOKE magnetic hysteresis amplitude changes significantly compared to uncoated Fe-Co/Si system. The results shows that the magneto-optical properties are significantly altered which indicates the presence of the interfacial Dzyaloshinskii–Moriya interaction.
