An attempt to apply a SQUID microscope for visualization of magnetic structure in giant magnetic impedance (GMI) elements was undertaken. The measurements were carried out on the 1 x mm thick permalloy strip with the inplane sizes 6 mm x 0.3 mm. The topography of the vertical component of magnetic field was imaged with a high spatial resolution close to 30 x mm over the central part of a sample. The images taken in the applied magnetic field varied over the range f 4 kAlm reveal the domain structure with anisotropy perpendicular to longitudinal sample axis.
