Topic: Magnetic properties of nanoparticles: what can we learn from Mössbauer spectrometry
Time: 9:30 AM, Sep. 20th (Wednesday)
Location: 910-308
Abstract
After a brief presentation of both the principles of the Mössbauer effect and the nature and origin of hyperfine interactions, we present the main relevant features to better investigate the magnetic properties of nanoparticles. We illustrate how both Mössbauer measurements performed as a function of temperature and external magnetic field combined with computer modeling calculations allow to understand some physical properties of magnetic nanoparticles.
