Abstract
An attempt to apply a SQUID microscope for visualization of magnetic struct ure in giant magnetic impedance (GMI) elements was undertaken. The measurem ents were carried out on the 1 x 10(-3) mm thick permalloy strip with the i nplane sizes 6 mm x 0.3 mm. The topography of the vertical component of mag netic field was imaged with a high spatial resolution close to 30 x 10(-3) mm over the central part of a sample. The images taken in the applied magne tic field varied over the range +/- 4 kA/m reveal the domain structure with anisotropy perpendicular to longitudinal sample axis.
