|Title:||Esr Of Gd3+ In The Kondo-lattice Compound Ybagcu4 And Its Reference Compounds Ragcu4 (r=y,lu)|
|Abstract:||Low-temperature (T<30 K) electron-spin-resonance (ESR) experiments of Gd3+ diluted in the Kondo-lattice compound YbAgCu4 and its reference compounds YAgCu4 and LuAgCu4 are interpreted in terms of an enhanced density of states at the Fermi level for the Yb-based compound. The results of susceptibility and ESR (Korringa rate and g-shift) measurements show negligible electron-electron exchange enhancement for all the studied compounds. The exchange interaction between the Gd3+ local moment and the conduction electrons (c-e) is c-e wave vector dependent in all three compounds.|
