|Title:||Electron spin resonance of Gd3+ and Nd3+ in LuInA(4) (A = Cu,Ni)|
|Abstract:||Low-temperature (1.6 K less than or similar to T less than or similar to 60 K) data of electron spin resonance for Gd3+ and Nd3+ diluted in LuInA(4) (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.
