The technology of annealing under stress on Fe 73.0 Cu 1.0 Nb 1.5 V 2.0 Si 13.5 B 9.0 amorphous ribbons was reported. By systematic study of the effects of the stress changes in 0 MPa^245 MPa at a fixed annealing temperature 540 ℃, on the magneto impedance response in Fe 73.0 Cu 1.0 Nb 1.5 V 2.0 Si 13.5 B 9.0 nanocrystalline ribbons had been investigated.It was found that the anisotropic field H k was under the controll of annealing stress and anisotropic field H k could be measured by the response of the magneto impedance in Fe based nanocrystalline ribbons.
