Abstract Amorphous Fe62-xNi19CoxCu0. 1Si3. 8B14Cr1. 1 (x=0, 1, 5, 10) ribbons were annealed under magnetic field and tensile stress, respectively, and their magnetic properties were investigated. Fe73. 5Cu1Nb3Si15. 5B7 and Fe66Ni10-Cu1Nb3Si11B9 nanocrystalline alloy ribbons were also fabricated for comparison. Excellent DC tolerant property was obtained in the amorphous FeNiCoCuSiBCr ribbons after thermomagnetic treatment and the constant permeable property was improved with increasing Co content. The relative permeability was constant up to the DC bias field of approximately 6��10-4, 9��10-4, and 10��10-4 T and the values of relative permeability ��r were 1650, 1200, and 1000 with the Co content being 0, 5 at. %, and 10 at. %, respectively. Besides, stress-annealed FeNiCoCuSiBCr alloy ribbons were proved to exhibit positive saturation magnetostriction constant ��s.
