High field antiferro-, ferri-and paramagnetic resonance at millimeter wavelengths

Abstract

Pulsed magnetic fields have been employed to " tune " the high frequency magnetic interactions of antiferro-ferri- and paramagnetic systems to 4 mm and 8 mm wavelengths. Examples of resonance experiments for each of these magnetic systems are given, the nature of the information obtained is reviewed, and results of these experiments are summarized. Related magnetic measurements are also described ; a detailed summary of susceptibility measurements for single crystal MnF2, CoF2 and Cr2O3 is given. Applications to high frequency devices are indicated
