Electron spin resonance spectroscopy extends to 1 THz range

Electron spin resonance (ESR) spectroscopy is based on the detection of resonance absorption of electromagnetic radiation corresponding to transitions between electron spin energy levels split by internal effects (e.g., crystal-field anisotropy, exchange interactions etc.) and/or by an applied magnetic field. The strength of such interactions in magnetic materials can vary from tens of millikelvin to hundreds of kelvin (which corresponds to a frequency range from tens of megahertz to tens of terahertz). That is why extending the frequency range of ESR techniques towards 1 THz (and beyond) appears to be one of the central issues in modern ESR spectroscopy.

Edinburgh Instruments have installed a FIRL100 CO2 far infrared (THz) laser system at Dresden High Magnetic Field Laboratory (HLD) at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR). The laser will be used for the multi-frequency pulsed-field (up to 70 T) ESR spectroscopy of strongly-correlated magnets, including low-dimensional and frustrated spin systems, high-Tc superconductors and related compounds, multiferroics etc.

Edinburgh Instruments hope that their FIRL-100 will help the Dresden High Magnetic Field Laboratory extend the frequency range of ESR techniques towards 1 THz.
