MILLIMETER-WAVE SPECTROSCOPY OF LOW-DIMENSIONAL MOLECULAR-METALS IN HIGH MAGNETIC-FIELDS

We have used a cavity perturbation technique to probe the electrodynam ic response of various low-dimensional molecular metals in high magnet ic fields. We discuss some of the technical aspects of these measureme nts and go on to present recent experimental data obtained in magnetic fields of up to 33 T. In addition to providing finite frequency infor mation in this frequency range, which is highly relevant to narrow ban dwidth conducting systems, we show how the extreme flexibility and sen sitivity of this technique offers great potential for probing the prop erties of novel materials in high magnetic fields.
