%X In this paper, the M?ssbauer spectra of a-Fe90-xCoxZr10(x = 0,4,10,20) and Fe90-yCryZr10(y= 4,7,13,16) alloys were studied at 77K. The results indicate that two different magnetic states exist in a-Fe-(Co, Cr)-Zr alloys, the dependence of hyperfine parameters on the average outer electron concentration a of the 3d TM atom show anomalies in the vicinity of a = 8, which implies the invar effect of a-Fe90Zr10 and a-Fe-(Co, Cr)-Zr with low Ca(Cr). The reduced temperature dependence of the reduced hyperfine field reveal the existence of amorphous ferromagnetism in a-Fe90-xCoxZr10(x = 10, 20) and the spin-grass-like behavior in a-Fe90-xCoxZr10(x = 0,4). A new magnetic structure model are suggested and discussed.
