In this paper, the M?ssbauer spectra of amorphous Fe90-xCoxZr10 (x=4, 10, 20,…70) and Fe90-yCryZr10 (y = 0, 4, 7, 16, 20) series of alloys were studied. The experimental results indicated that, a-Fe90-yCryZr10 and a-Fe90-xCoxZr10 in Fe-rich regions contain two different local coordination structure, which produce both ferromagnetic and antiferromagnetic states below Tc and different paramagnetic states above Tc. When x is above 30, in a-Fe90-xCoxZr10 alloys exists only one ferromagnetic state, which implies magnetic "homogeneity". The micro-structures of amorphous transition metal (TM)-TM alloys were discussed in some detail.
