The nuclear magnetic resonance (NMR) study has been made for the "Mnand "Fe nuclei in disordered ferromagnetic alloys (Fe.-.Cr,)..ggMn.... (x<0.3)by the spin echo method in zero external magnetic field at 1.7 K. The frequencycorresponding to the center of gravity of the "Mn NMR spectrum increases from239.9 MHz at ,X'=0 up to a maximum value of 267-35 MHz at .X'=O.20 with in-creasing x and then decreases down to 236.4 MHz at ,X'=0.30. The deduced valueof the Mn magnetic moment increases monotonically from 0.72 p. at .r=0 withincreasing x, passes a maximum value of 1.33 jt. at ,X'=0.20 and then dedreases to1.2 /ZB at .Xl=0.30. This variation of the Mn moment with x is correlated withthat of the Cr magnetic moment, and it is suggested that the moment of the Mnimpurity is more localized in alloys with a higher Cr content. The "Fe NMRspectrum is also discussed.
