EMR Instrumentation

Electron Magnetic Resonance (EMR) includes conventional ESR/EPR, ferro/antiferromagnetic resonance, ferrimagnetic resonance and electron cyclotron resonance. For g=2 systems the combination of high magnetic field and high frequency is expected to increase resolution (when the linewidth is independent of the magnetic field, as for hyperfine interactions), and to increase sensitivity.

For field induced transitions (one-dimensional antiferromagnetism, organic conductors), the motivation for high-field experiments derives principally from the magnetic field dependence of the spectra. For large Zero Field Splitting systems that are spectroscopically silent at low frequency, the motivation obviously lies in the frequency dependence of the spectra.

Instrumentation for EMR is being developed for use before June, 1996. It will use a 15/17 T dedicated superconducting magnet and the general purpose DC resistive magnets.
