High-frequency magnetic resonance of molecular spin systems (B03)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2017
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 314695032

Magnetic resonance spectroscopy offers a way to probe electronic spin states either directly, through absorption and emission of electromagnetic radiation, or indirectly, through a change in macroscopic observables such as electrical conductivity or light emission intensity. The higher the frequency of the resonant radiation, the greater the spectral resolution achievable, enabling differentiation between hyperfine and spin-orbit coupling (SOC) induced spectral broadening. Using a custom-designed 350 GHz spectrometer, we will investigate SOC effects in materials with very weak nominal SOC, such as organic semiconductors.
