Electron Spin Resonance Of Gd3+ And Nd3+ In Luina4 (a = Cu,ni)

Low-temperature (1.6 K≲T≲60 K) data of electron spin resonance for Gd3+ and Nd3+ diluted in LuInA4 (A = Cu,Ni) compounds are presented. The results are interpreted in terms of a density of states at the Fermi level built up of a single s band for the Cu-based system and a multiple (s and d) bands for the Ni-based system. The susceptibility and specific heat data show negligible electron-electron exchange enhancement for both compounds. For the Cu-based system the exchange interaction between the rare-earth (Gd3+ and Nd3+) local moment and the conduction electrons depends on the conduction-electron wave vector. ©1999 The American Physical Society.60191351513519Taylor, R.H., (1975) Adv.
