El grup de recerca desenvolupa la seva activitat en dos vessants de la ciència dels materials. D'una banda estudia el comportament tèrmic dels aliatges ferromagnètics i de l'altra, les propietats estàtiques i dinàmiques de materials dielèctrics complexos formats per cristalls líquids i cristalls líquids confinats en sistemes micro i nanoestructurals.

El grupo de investigación desarrolla su actividad en dos aspectos de la ciencia de materiales. Por una parte, estudia el comportamiento térmico de las aleaciones ferromagnéticas y por otra, las propiedades estáticas y dinámicas de materiales dieléctricos complejos formados por cristales líquidos y cristales líquidos confinados en sistemas micro y nanoestructurados.

The research group develops its activity in two basic aspects from teh materials science. On the one hand, the group studies the thermal behaviour of ferromagnetic alloys and ono the other, the static and dynami properties of complex dielectric materials made up of liquid crystals and liquids crystrals confined to micro and nanostructured systems.
