ABSTRACT: Commercial cobalt-iron-oxide particles for digital applications
have been examined by several techniques: physisorption, mercury
porosimetry, and electron microscopy. Surface properties, in particular
acicularity and heterogeneity, are related to the rheological behavior
of the powders, to their magnetic characteristics, to the
characteristics of draw-down coatings, and to the response of
experimental floppy disks at predetermined recording frequencies.
Particles showing high and uniform dispersibility have a narrow particle
size distribution and a relatively large number of high-energy sites

ABSTRACT: Alloy thin films of interest for possible electronic applications were obtained by electrodeposition: NiFe for magnetic heads, Co alloys for magnetic recording and CuSb as a possible underlayer for electric contacts. Permalloy ECD NiFe films were deposited from acid baths on Si wafers, patterned by photolithography; CoPt and CoPd films from baths of similar composition, obtaining hard CoPt and soft CoPd layers; CuSb as oversaturated solid solutions or as multilayers depending on the deposition conditions. Electrokinetic behaviour and related structures are interpreted by means of the normality-inertia parameter Pni.
