· JVASP-51740· YbMgNiH4

YbMgNiH4 is an experimental metal hydride compound combining ytterbium, magnesium, nickel, and hydrogen. This material belongs to the ternary hydride family, which is primarily of research interest for hydrogen storage applications and fundamental studies of metal-hydrogen interactions. Though not yet commercialized, compounds in this family are investigated for energy storage systems and as model materials for understanding how hydride phases behave under pressure and thermal cycling.
