Capturing magnetic domain structures (IMAGE) Advanced Devices & Instrumentation Caption (A) a single magnetic domain and (B) multiple magnetic domains with opposite polarization. (C) Following the subtraction of image (A) from image (B), a Kerr image with sharp contrast is obtained [39]. (D) The magnetic domains in Ta/CoFeB/Ta stack with in-plane uniaxial anisotropy [40]. (E) The magnetic domains in the surface of polished NdFeB. (F) The magnetic domains in the silicon steel observed by Kerr microscope assisted by MOIF.
