Further Information

Electron Magnetic Resonance

Electron magnetic resonance (EMR) includes electron spin resonance (ESR) and cyclotron resonance (CR) and can be performed in pulsed magnetic fields using a transmission-type tunable-frequency spectrometer operated in two frequency ranges: Range A: ~100 - 600 GHz (VDIs and Gunn-diodes), range B: 1.2 - 9 THz (free electron laser). The spectrometer is equipped with Ca:Ge and n-InSb bolometers. EMR experiments are best suited for magnet types A or B (needs a 24 mm bore). The lowest temperature available for EMR experiments is 1.5 K (range A) and ~ 5 K (range B). The maximum sample size is ~ 3 mm outer diameter (see Ref. [1] for further information).

To perform experiments you are required to submit a proposal for magnet time http://www.emfl.eu/user.html. For EMR experiments in range B you are required to submit in addition another proposal requesting FEL beamtime http://www.hzdr.de/db/Cms?pNid=1732.
