In-Plane Magnetic Anisotropy Detection of Crystal Grain Orientation in Goss-Textured Ferromagnets

In this paper, a preliminary study about non-destructive diagnostics of crystal grain orientation in laminated Goss-textured magnetic material is presented. The reconstruction of the local lattice orientation is achieved by exploiting the surface magnetic anisotropy that is obtained by the contact-less magnetic measurements and lag angle plots elaboration. In addition, the experimental measurements are compared to the magnetic simulations of the crystal grains in order to extrapolate the local orientation of the system. The evaluation of the tilt angle between the easy axis and the rolling direction, as well as the angle of the other axes respect to the lamination plane, is carried out for different grains of an Fe-Si grain-oriented alloy specimen.
