Thermoremanent Co nanoparticles (25-30 nm) were synthesized by the thermal decomposition of Co2(CO)8 in the presence of calixarene-derived surfactants 1 . They self-assemble into ring structures comprising 5-11 particles when dispersed in a toluene s

An overview of the conception and development of the MIDAS system at Arizona State University is given: a Microscope for Imaging, Diffraction and Analysis of Surfaces. John Cowley's vision in the early 1980s was ambitious and far-reaching, and it was

Off-axis electron holography and micromagnetic simulations have been used to investigate magnetization reversal mechanisms and remanent states in exchange-biased submicron Co84Fe16/Fe54Mn46 patterned elements. Domain structures within the elements we

Magnetic domain structures in two 50 nm thick chemically-ordered FePd (0 0 1) epitaxial films with different perpendicular anisotropies have been studied using Lorentz microscopy. Domain and domain wall structures vary significantly according to the

The interlayer coupling and magnetization reversal of patterned, submicron Co/Au/Ni nanostructures, shaped as diamonds, ellipses, and rectangles, have been investigated using off-axis electron holography and micromagnetic simulations. Antiferromagnet

Since its introduction 40 years ago Lorentz microscopy has been used extensively to study domain structures in magnetic thin films and elements. Here we review the principal imaging modes, with emphasis on those introduced most recently, and discuss

The design of a high resolution photoemission electron microscope (PEEM) for the study of magnetic materials is described. PEEM is based on imaging the photoemitted (secondary) electrons from a sample irradiated by x rays. This microscope is permanen

We present the first images of a surface showing clear antiferromagnetic contrast. The images were obtained for 10[endash]80thinspthinspnm thick NiO(100) films grown on Mg(100) by means of x-ray magnetic linear dichroism spectroscopy in conjunction w

A review is given of the principles underlying X-ray magnetic circular (XMCD) and linear (XMLD) dichroism spectromicroscopies consisting of polarized X-ray absorption spectroscopy in conjunction with scanning or imaging microscopy. The techniques are
