[en] The magnetic susceptibility and electrical resistivity of amorphous (Cu/sub .57/Zr/sub .43/)/sub 1 - x/M/sub x/ alloys, where M expresses 3d transition metal impurities of V, Cr, Mn, Fe, Co and Ni, were measured. The host Cu/sub .57/Zr/sub .43/ alloy shows temperature independent Pauli paramagnetic behavior. The addition of 3d impurities only slightly affects the value of the susceptibility which still remains temperature independent except for Mn, showing that these 3d impurities have no localized magnetic moment in this amorphous alloy. The susceptibility of amorphous Cu--Zr containing Mn can be expressed as the sum of a temperature independent part, and a temperature dependent part which obeys the Curie Weiss law. The effective magnetic moment per Mn atom is about 1.6 μB
