Abstract

"FLUIDO MAGNéTICO". A presente invenção refere-se a um meio fluido magnético que compreende uma pluralidade de partículas ferro- ou ferrimagnéticas, cada uma das partículas apresentando uma maior dimensão não superior a 100 nm, ditas partículas sendo preparadas por um processo que inclui a etapa em que as partículas são formadas dentro de um invólucro macromolecular orgânico."MAGNETIC FLUID". The present invention relates to a magnetic fluid medium comprising a plurality of ferro- or ferrimagnetic particles, each of the particles having a greater dimension not exceeding 100 nm, said particles being prepared by a process that includes the step in which the particles are formed within an organic macromolecular envelope.
