“…Another approach to extend the frequency range of spectrometers used to study resonance phenomena in steady as well as in pulsed magnetic fields is the employment of tunable-frequency THz-range free electron lasers (FEL). Although the idea of using FELs as THz radiation sources in magnetic resonance techniques seems, at the first glance, very straightforward and some attempts have been already made [43][44][45][46], until recently it has remained questionable whether a sufficiently high resolution required for most ESR applications (at least better than 1%) can be achieved. It is worth to mention that in contrast to radiation produced by conventional sources (for instance, Gunn-diodes) employed for continuous-wave (cw) ESR spectroscopy, the FELs are operating in a pulsed regime.…”

The employment of the high-magnetic-field resonance spectroscopy to probe magnetic excitations in the THz frequency range is reported. To illustrate the great potential of this technique in solid state physics, we present results of recent electron spin resonance studies of the quantum-tunneling effect in the single-molecule magnet Mn12tba and of the soliton-magnon crossover in Cu-PM, a spin-1/2 Heisenberg chain system with a staggered transverse field. Among others, we report on the successful use of the THz-range timedomain and free electron laser spectroscopy to study magnetic excitation spectra in pulsed magnetic fields.

“…The first attempt to combine FEL and pulsed magnetic fields was made using the FELIX radiation source at Rijnhuizen [15,16,17,18]. Although the idea of employing FELs as THz radiation sources in ESR spectroscopy seems, at the first glance, very straightforward, it has remained questionable whether a sufficiently high resolution required for most ESR applications (at least better than 1%) can be achieved.…”

The successful use of picosecond-pulse free-electron-laser (FEL) radiation for the continuous-wave THz-range electron spin resonance (ESR) spectroscopy has been demonstrated. The combination of two linac-based FELs (covering the wavelength range of 4 -250 µm) with pulsed magnetic fields up to 70 T allows for multi-frequency ESR spectroscopy in a frequency range of 1.2 -75 THz with a spectral resolution better than 1%. The performance of the spectrometer is illustrated with ESR spectra obtained in the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and the low-dimensional organic material (C6H9N2)CuCl3.
