Abstract
Results of cw63Cu NMR measurements in dilute CuFe alloys containing from 0.01 up to 0.2 at.-% Fe are presented. The temperature was well above the Kondo temperature of this specimen. The broadening of the NMR line width is caused by the localized magnetic moment of the Fe impurities. The decreasing signal amplitude with increasing iron content is due to the quadrupolar interactions appearing simultaneously. The line broadening correspond strongly to that of the impurity susceptibility behaviour in CuFe. The quadrupolar disturbances are temperature independent. The influence of the simultaneously appearing magnetic and electric interactions on the spin lattice nuclear relaxation time is discussed.
