· JVASP-140846· Nd2Fe15Si2H2

Nd2Fe15Si2H2 is an intermetallic hydride compound combining rare-earth neodymium with iron and silicon, representing a research-phase material in the permanent magnet and hydrogen storage material families. This composition is primarily of academic and developmental interest for exploring magnetic properties and hydrogen absorption behavior in rare-earth iron systems, with potential applications in advanced magnetic devices or energy storage, though it has not achieved widespread industrial adoption compared to conventional Nd-Fe-B permanent magnets.
