    • Phys. phenomena in high magnetic fields

Research Equipment Available

        DC fields:
      • 16 T tunable-frequency ESR spectrometer: ~100 GHz - 1.3 THz (VDIs, BWOs, MVNA); 1.4 - 300 K; Voigt/Faraday geometries, AM/FM modulations.
      • X-band Elexsys 500 Bruker spectrometer: 2 - 300 K; 1.8 T; goniometer.
      • BWO-based 10 T frequency-domain spectrometer: 2 - 300 K, ~100 GHz - 1.3 THz split-coil magnet with optical access, Voigt/Faraday geometries.

      • 64 T pulsed-field ESR spectrometer: ~100 - 600 GHz (VDIs), 1.2 - 9 THz (free electron laser,  FEL). The pulsed-field spectrometer* is a user facility. To perform ESR/CR  experiments in pulsed fields up to 63 T please submit your proposal for magnet time  If you want to use FEL  please submit the second proposal*
      • Important: when planing your experiments please take into account that the minimal tempertaure available for pulsed-field experiments is 1.4 K (conventional radiation sources) and 5 K (FEL)

Ph.D. student position available

In the frame of the DFG project "Spin dynamics and magnetism of spin systems with frustrations" the Electron Spin Resonance group has an opening for a Ph.D. student  position in quantum and frustrated magnetism, beginning June 1, 2016. The position is for three years. Applicants should provide Curriculum Vita, cover letter with a statement of research interest and scientific background, and have a reference letter from her/his Diploma/Master supervisor provided separately. The application materials should be submitted in electronic (PDF) format through email, to Sergei Zvyagin. Screening of applications will start as they arrive, so early applications are encouraged.
