· YNi

YNi is an intermetallic compound combining yttrium and nickel, belonging to the rare-earth intermetallic family. This material is primarily of research and specialized industrial interest, used in hydrogen storage applications, magnetocaloric devices, and advanced functional materials where the unique coupling between magnetic and thermal properties is exploited. YNi and related yttrium-nickel phases are notable for their potential in hydrogen absorption/desorption cycles and magnetothermal applications, making them candidates for next-generation energy storage and refrigeration technologies, though they remain less common than conventional structural metals in mainstream engineering.
