THIS IS A PAST EVENT.

Colloquium - Dr. Mykhaylo Ozerov, National High Magnetic Field Laboratory, "Magnetic Resonance in Far Infrared Spectral Range" (host S. Winter)

Abstract:

Magnetic resonance is a physical phenomenon that occurs across a wide spectral range of the electromagnetic radiation. Far-infrared magneto spectroscopy (FIRMS) offers an experimental routine to probe the magnetic excitation spectrum between 0.4 and 22 THz (12- 720 cm-1). In this talk, I will discuss the FIRMS technique employed at the National High Magnetic Field Laboratory, with a specific focus on how it has been successfully applied to the study of single-molecule magnets and low-dimensional spin systems. A short introduction includes a description of the measurement procedure, the data analysis and a recent sensitivity improvement. The advantages and limitations compared to other spectroscopic techniques are presented as well. The selected examples illustrate how the FIRMS technique allows direct measurements of zero-field splitting energy and enables the accurate determination of spin-Hamiltonian parameters, particularly when combined with high-frequency EPR data. Finally, the manifestation of spin-phonon coupling effects will be shown in the FIRMS spectra.
