摘要

Heavy fermion CeCu4Al compound has been studied by inelastic neutron diffraction (INS), heat capacity and magnetic susceptibility measurements. A single Crystal Electric Field (CEF) peak has been detected in the INS spectra, which may be explained by a quasi-quartet state suggested by the analysis of the Schottky anomaly contributing to the magnetic part of the specific heat. The Kondo interactions have been included in the analysis of the magnetic part employing the simplified resonance level model. The resulting Kondo temperature of about 5-10 K is somewhat larger than in the previous studies. The magnetic susceptibility confirms the CEF level scheme of the type 0-93 K and provides the values of the CEF parameters.
