摘要: Publisher Summary This chapter discusses the properties of rare earth hydrides in terms ionic bonding rather than band structure. The Eu and Yb is decidedly more ionic; they resemble alkaline most their properties. attributed to stability underlying 4f states because are fully occupied case half-occupied (one electron each orbital according Hund's rule) Eu. characteristics have been extensively reviewed past by Bos Gayer Mueller, information has updated Libowitz. Consequently, emphasis will be placed on work published subsequent those dates. summarizes magnetic then compares them with metals. decrease susceptibility metal hydride formation, which characteristic transition hydrides, occurs only heavier metals (Gd Tm) including yttrium. lighter earths Ce, Pr, Nd, Sm show essentially no change formation.
