Advances in Magnetic Microscopy

A remarkable number of methods for direct, real-space imaging in
magnetic microscopy have been demonstrated over the past decade and a
half, and the pace of development shows no sign of slowing. Our
understanding of magnetism increases as each striking new image of
surface and thin-film magnetization is obtained. The continued
development of high-performance magnetic information technologies also
requires detailed study of the magnetostatics and dynamics of
microscopic magnetic structures. Both fundamental curiosity and
practical interest now drive us toward innovations in magnetic
microscopy for nanometer-length scale and femtosecond temporal
resolutions, which are beyond the limits of traditional imaging
techniques. This survey is intended to provide an overview of the
motivations, accomplishments, and future prospects for this discipline.
