Magnetic dynamics in correlated electron metals poised between localization and itinerancy

Pressure effects in CeNi

“…The nature of these transitions is not understood completely, however similar character of the 4f and 5f electrons encourages joint study of phase transition mechanisms in Pu, Ce and their compounds. Low temperature bulk properties and a degree of the f-electron shell delocalization of the intermediate-valence compound CeNi remind the properties of metallic plutonium [1]. Moreover, CeNi undergoes a pressure-induced first-order volume-collapse phase transition [2].…”

Kondo universality and energy scales in plutonium

“…In our preceding paper [7] we used CeNi as a homolog of Pu. It seems that cerium in CeNi has almost the same degree of delocalization of the f-electrons as d-Pu.…”
