| Popis: | Structural and magnetic properties of rapidly quenched amorphous alloys were investigated as a function of the iron content (x = 0 to 20). The observed dependence of the atomic pair correlation functions on the Fe content points to the random incorporation of the iron atoms into the amorphous structure. The magnetic behaviour is dominated by temperature independent Pauli paramagnetism in the range . Magnetic clusters are determined for x = 20. The appearance of these iron clusters is consistent with the observed random distribution of iron atoms in the amorphous alloy. The minimum size of an iron cluster required for the creation of a non-zero magnetic moment amounts to about 100 atoms. |
