As part of a program to develop iron particles for next generation
recording disk medium, their structural properties were investigated using
transmission electron microscopy and electron diffraction. Iron particles
are a more desirable recording medium than iron oxide, the most widely used
material in disk manufacturing, because they offer a higher magnetic output
and a higher coercive force.
The particles were prepared by a method described elsewhere. Because of
their strong magnetic interaction, a method had to be developed to separate
the particles on the electron microscope grids.
