Abstract Effect of impurity Zr on the magnetic properties, electrical resistivity and thermal stability of amorphous Fe_(82-x)Zr_xSi_5B_(13) (x =0.02, 0.16, 0.87) alloys has been studied. It was observed that while the Zr content in the alloys increases from x=0.02 to 0.87, the crystallization temperature, T_(cr), increases from 755 to 782K at a rate on heating of 10 K/min, and the saturation magnetization, σ(RT), at room temperature also the Curie temperature, Te, decrease 3% and 4.5% respectively. The fluctuation of the exchange interaction of the alloys is increased by the increase of Zr addition. The resistivity minimum was also obtained at low temperature of 15K in the alloy containing Zr=0.87. It seems to attribute this to Kortdo-like effect.
