Magnetické nanostruktury

Vědecké zaměření

Skupina se dlouhodobě věnuje studiu magnetických vlastností různých nanostrukturních materiálů na bázi železa, nehydratovaných forem oxidů železa a uhlíku a jejich hybridů, zahrnující rovněž molekulární komplexy. Významná pozornost je přitom věnována pochopení mechanismů řídicích magnetické vlastnosti (nano)materiálů, popisu magnetického chování v nanosvětě a identifikování parametrů, kterými lze příhodně ladit magnetické vlastnosti s ohledem na aplikovatelnost (nano)materiálu. Možnost využití takovýchto (nano)materiálů přitom postihuje různá odvětví v oblastech technologických, medicínských a environmentálních. Pro magnetickou charakterizaci (nano)materiálů skupina využívá široké spektrum experimentálních technik, mezi něž patří Mössbauerova spektroskopie v různých experimentálních podmínkách (měření při pokojové, nízké a vysoké teplotě, měření ve vnějších magnetických polích, in-situ měření apod.), magnetometry (indukční magnetometr typu SQUID, PPMS) a elektronová paramagnetická rezonance. Skupina rovněž disponuje přístroji pro TG a DSC analýzy. Aktivity skupiny rovněž zahrnují simulační a teoretické studie, jejichž cílem je konstrukce modelů popisujících magnetické chování převážně uhlíkových nanostruktur. Mimo výzkum se skupina aktivně podílí na vývoji a konstrukci mössbauerovských spektrometrů, které jsou prodávány po celém světě.
