Abstract
A technique is described which uses a scanning column magnetometer to obtain a magnetic profile of a column of dispersion of magnetic record ing particles. By comparing profiles as a function of time, settling o f particles can be observed. Analysed data for different dispersions c an provide a comparison of their stability. The technique has the pote ntial to combine data with rheological properties and, using hindered settling theory, to analyse the structure of magnetic particle cluster s in the dispersion. This will assist in understanding tape-production processes such as orientation, surface conditioning and drying. (C) 1 998 Elsevier Science B.V. All rights reserved.
