摘要：

The surface state of palladium-based alloys, specifically Pd-6.0In-0.5Ru and Pd-7.0Y (the element content is given in wt %) has been studied using magnetic force microscopy (MFM) and atomic force microscopy (AFM). The study was conducted within the framework of the current trend to enhance the safety of hydrogen separation and storage. The samples for the study were made of high-purity metals through arc alloying. They underwent reversible hydrogen alloying to investigate the impact of internal deformation of metal systems on their structure-sensitive properties. The study demonstrates the characteristics of the sample surface morphology and domain structure before and after hydrogenation. The local magnetic properties of alloy surfaces have been clarified, and their changes as a result of hydrogen exposure have been identified.
