ABSTRACT:
Coated magnetizable particles of sub-micron size are used to form reversible suspensions in which the particles may be magnetically aggregated and thereafter resuspended as desired. Each microparticle comprises a core composed essentially of a magnetically-responsive material having a Curie temperature within the range of about 5.degree. to 65.degree. C. and a magnetic moment at saturation of at least 2.0 .mu..sub.B at 4.2.degree. K., and a coating about the core formed of a solid cross-linked polymeric material having chemically reactive groups at the surface thereof.
