Our works discuss the magnetic characteristics of wasp-waisted hysteresis loops and outline a rationale for this type of behavior by superposition of hard and soft magnetic phases. Because of the absence of magnetic interactions between particles, in measurement procedure, we could sum the magnetization mathematically of the isolated particles at each field value to create a composite hysteresis loops.

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.
