Resumen
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. 56 14 8933 8937 Falicov, L.M., Hanke, W., Maple, M.B., (1981) Valence Fluctuation in Solids, , North-Holland, Amsterdam Wachter, P., Boppart, H., (1982) Valence Instabilities, , North-Holland, Amsterdam Muller-Hartmann, E., Roden, B., Wohlleben, D., (1984) Valence Fluctuation, , North-Holland, Amsterdam Barberis, G.E., Foglio, M.E., Crow, J.E., Schlottmann, P., (1991) Valence Fluctuations, , North-Holland, Amsterdam Kojima, K., Nakai, Y., Sizuki, T., Asano, H., Izumi, F., Fujita, T., Hihara, T., (1990) J.
