EPR – electron paramagnetic resonance, FMR – ferromagnetic resonance, impedance spectroscopy and magnetoelectric effect measurement systems

The Bruker EleXsys E500 EPR spectrometer functions in two frequency bands – X (~9.5 GHz) and Q (~34 GHz) – and is equipped with a computerised goniometer and two continuous flow cryostates working with N₂ and He, covering a temperature range from 3.7 to 600 K. The maximum magnetic field amounts to 15 kG. Besides EPR, the spectrometer also allows measurements of the ferromagnetic resonance. The home-made magnetoelectric effect spectrometer equipped with an ARS closed cycle He cryostate allows electrical (impedance) and magnetoelectric measurements in a temperature range from 10 to 450 K.
