Current Research Interests

    • Quantum cooperative phenomena in low-D spin systems
    • Frustrated spin systems
    • Phys. phenomena in strongly-correlated electron systems
    • 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.
      • Pulsed fields:
      • 64 T pulsed-field ESR spectrometer: ~100 - 600 GHz (VDIs), 1.2 - 9 THz (free electron laser, FEL), 0.4 - 3.5 THz (FIRL-100 molecular laser). 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 http://www.emfl.eu/user.html. If you want to use FEL please submit the second proposal* http://www.hzdr.de/db/Cms?pNid=1732
      • 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)
