The results show that with the increase of deformation strains and thinning of Fe-Cr fibers, the saturation magnetization are about 140 A·m2/kg constantly, and the remanent magnetism and coercivity increase gradually.The magnetic properties of Fe-Cr fibers are invariant when the Fe-Cr fibers were preserved in absolute alcohol or air for more than 1 a. After Fe-Cr fibers heated in air at temperature higher than 300 ℃ for 1 h, the Fe-Cr fibers transform from ferromagnetic α-solution to paramagnetic2O3, and the saturation magnetization of samples decreases remarkably. With the increase of deformation strains, the thermal stability of thinner Fe-Cr fibers decreases.
