... 2 MAGNETIC FLUIDS:
Magnetic fluids ( MF ) are stable colloidal suspensions of ultrafine ferro- or ferri- magnetic particles ( D100Ao ), coated with a surfactant like oleic acid, in a suitable liquid carriers such as Isopar-M, kerosene, decalin, etc. ...
The special feature of magnetic fluids is given by the fact, that they combine normal liquid behavior with superparamagnetic properties, as will be discussed later. The possibility of magnetic fluid control gave rise to the development of many technical applications in our everyday life [1-3]. ... Since this is much smaller than the size of a single magnetic domain in bulk solids, which is about , the magnetization of the individual particle is saturated, but the direction of the magnetic moment is subject to thermal agitation [1,2,5].
