文摘

Comparison of magnetic microstructure with neutron diffraction stress analysis. High spatial resolution magnetic stray field images of hypereutectoid TIG welds. Spatial variations of the stray fields are below the magnetic field of the earth. GMR spin valve gradiometer arrays adapted for the evaluation of magnetic microstructures. Magnetic stray fields are closely linked to microstructure of the material.
