摘要：
The invention, "nanoparticulate magnetic material for thermal applications", pertains to the field of specific uses or applications of nanostructures formed by individual manipulation of groups of atoms or molecules as discrete magnetic units composed of metals of the lanthanide group, and relates to a nanoparticulate material coated with an organic or inorganic compound, or with a combination thereof, for heating a localised point or a localized zone on an object exposed to an alternating magnetic field. The product consists of a particulate material, optionally including a biocompatible, organic and/or inorganic coating made from an alloy composed of at least one element of the lanthanide group (LA), at least one transition metal (MT) and at least one metalloid (ML), and represented by LA-MT-ML. The described material can be produced by a physical or a chemical process, or by a combination thereof, and has the novel and inventive feature of allowing the alloy to be heated in a controlled manner, alloy that can be produced from a mixture of pure elements, a mixture of alloys or by recycling already industrialised products. The product described in this patent can be used in applications requiring localised heating or localised magnetic features, such as resin or cement hardening, and in medical applications for the treatment of tumours or imaging diagnosis by means of contrast agents.A invenção "MATERIAL MAGNÉTICO NANOPARTICULADO PARA APLICAÇÕES TÉRMICAS", pertencente ao setor de usos específicos ou aplicações de nanoestruturas formadas por manipulação individual de grupos de átomos ou moléculas como unidades discretas magnéticas compostas de metais do grupo dos lantanídeos, refere-se a material nanoparticulado recoberto por composto orgânico ou inorgânico ou combinação, para aquecimento localizado de um objeto ou região localizada quando expostos a um campo magnético alternado.
