"Advanced X-ray spectroscopy as a tool to probe magnetic properties 
with element specificity"

címmel előadást tart az MTA KFKI RMKI tanácstermében (KFKI III. épület 2. 
emelet) február 17-én, csütörtökön 10:00-kor.

Az előadás összefoglalója:

X-ray absorption (XAS) and emission (XES) spectroscopies give element 
and symmetry sensitive insight into the electronic structure of matter. 
Using intensive hard X-rays produced by modern synchrotron sources, bulk 
and surface properties of solid and liquid phases may be studied in situ 
in demanding sample environments, e.g. extreme temperatures, high 
pressure, high magnetic field, etc. The experimental and theoretical 
aspects of XAS, XES and their Magnetic Circular Dichroism (XMCD) will be 
presented and illustrated with specific examples - tracking of spin state 
and charge transfer in mixed valence manganites and cobaltates, magnetic 
field induced phase transition in magnetoresistive double perovskites, and 
site specific magnetometry in ferrites.


Minden érdeklődőt szívesen látunk.
