Primer mehkih materialov so tekoči kristali, ki imajo močan elektro optični odziv, in jih množično uporabljamo v sodobnih zaslonih ter ferofluidi, ki se odzivajo na magnetno polje in jih uporabljamo ''kot tesnila, pol-aktivne dušilce, v sistemih za namestitev in kot transportne medije.'' Feromagnetni tekoči kristali, ki smo jih nedavno razvili na Institutu Jožef Stefan so hibridi med tekočimi kristali in ferofluidi in se odzivajo tako na električno kot na magnetno polje. V projektu se bomo osredotočili na razvoj in razumevanje mehkih materialov z veliko magnetizacijo in močnim odzivom na električno polje. Do sedaj razviti feromagnetni tekoči kristali imajo bodisi majhno magnetizacijo in močan odziv na električno polje bodisi veliko magnetizacijo in zelo šibek odziv na električno polje. '''Cilj''' predlaganega projekta je razviti materiale, ki imajo lastnosti obeh in ki jih bomo lahko uporabili v napravah, kjer potrebujemo krmiljenje magnetizacije, npr. v nerecipročnih napravah za informacijsko tehnologijo ali v izvorih majhnih magnetnih polj.
