Abstract

We report ESR study of Gd and Nd in RCo₂ and RNi₂ (R = Sc, Y, Zr, Lu, Ce) compounds. The variation of the Gd g shift from RCo₂ to RNi₂ compounds is consistent with a recent calculation of the density of states and also with the systematic behaviour demonstrated previously by us for transition metal intermetallic compounds. The Nd resonance in CeNi₂ and LuNi₂ indicate Γ₆ ground state crystalline field splitting; the Nd g value in YNi₂:Nd and LuNi₂: Nd is anomallous. Several possibilities for this anomally are discussed.
