INVESTIGATION OF MICROWAVE NON-LINEAR EFFECTFERROMAGNETIC MATERIALS.

Abstract

Operation of the ferrite parametric amplifier on magnetodynamic modes below the low frequency boundary of the Suhl spinwave manifold has been successfully obtained. Both quasi-degenerate, and non-degenerate operation for which both signal and idler resonances lie (in frequency) below the Suhl spinwave manifold are reported. Pump power was as low as 67 watts with gain in excess of 20 db. Minimum pump power occurred for a magnetic bias field of 6890 Oe, well above the limiting field for first order spinwave degener acy of 6798 Oe. A summary is presented covering the work performed in harmonic generation and parametric amplification utilizing non-linear effects in ferrimagnetic materials. Results of theoretical developments and of experimentation are presented in equation form.
