Abstract

Various magnetic measurements on CeCu5-xAlx, x = 0, 1, 1.5, 2, indicate that increasing Kondo interaction due to Cu/Al substitution causes a substantial decrease of the magnetic moment in the crystal-field ground state. A theoretical description on the basis of the non-crossing approximation, taking into account the primary interaction mechanisms, yields excellent agreement with the data and shows that the moment is reduced even at high values of applied magnetic field.
