bo v torek, 4. decembra 2012, ob 14. uri v Veliki predavalnici Instituta
>Jožef Stefan< na Jamovi cesti 39 v Ljubljani. Napovednik predavanja najdete
tudi na naslovu http://www.ijs.si/ijsw/Koledar_prireditev, posnetke

Fizika, kemija in veda o materialih v zelo močnih magnetnih poljih: NMR in
onstran

 

Močna magnetna polja so eno najzmogljivejših orodij za raziskave,
modifikacije in nadzor nad agregatnimi stanji snovi. Sodobni komercialni
superprevodni magneti dosegajo gostote do 23 T, močnejša polja pa ustvarjajo
le maloštevilne specializirane ustanove. V Evropi so trije večji
laboratoriji za močna polja, do katerih imajo dostop tudi zunanji
uporabniki: HLD v Dresdnu, HFML v Nijmegnu in  LNCMI v Grenoblu in Toulousu,
ki so odnedavna združeni v European Magnetic Field Laboratory (EMFL).
Najprej bomo predstavili infrastrukturo v grenobelskem laboratoriju EMFL in
razpoložljive eksperimentalne tehnike. Nato se bomo osredotočili na jedrsko
magnetno resonanco (NMR) v zelo močnem polju, ki je zmogljiva mikroskopska
metoda za študij mnogih problemov v fiziki, kemiji in na področju
materialov. Nedavno smo grenobelske aparature za NMR razširili, da dosežejo
zelo visoka polja s (35 T) in frekvence (1.5 GHz), zelo nizke temperature
(50 mK) in izboljšali občutljivost in ločljivost (10 ppm). Z izbranimi
nedavno zaključenimi projekti bomo prikazali zmogljivosti sedanjih naprav za
NMR.

Predavanje bo v angleščini.

Lepo vabljeni!

Physics, chemistry and materials science in very high magnetic fields: NMR
and beyond

 

High magnetic fields are one of the most powerful tools to study, modify and
control the different states of matter. Whereas commercial state-of-the-art
superconducting magnets reach magnetic fields up to 23 T, higher fields are
only available at a small number of specialized large-scale facilities. In
Europe there are three major high field laboratories providing access for
external users: HLD Dresden, HFML Nijmegen and LNCMI Grenoble-Toulouse,
recently united in the European Magnetic Field Laboratory (EMFL). First, we
will present the infrastructure of the Grenoble EMFL laboratory and its
available experimental techniques. Second, we will focus on very high field
solid-state nuclear magnetic resonance (NMR), a powerful microscopic method
for investigating many problems in physics, chemistry and materials science.
Recently, the options for NMR at Grenoble have been extended to very high
magnetic fields (35 T) and frequencies (1.5 GHz), to very low temperatures
(50 mK) as well as towards enhanced sensitivity and resolution (10 ppm).
Using selected recent research projects we will demonstrate the potential of
the available NMR instrumentation.

 

 

We look forward to meeting you at the "Kolokvij na IJS"!
