In November 1946, under the title of 'Anomalous high frequency resistance of ferromagnetic metals', Nature carried the announcement of the discovery of what is now called ferromagnetic resonance. The discovery was made by Dr J H E Griffiths who died

Low power microwave absorption and dispersion measurements have been made on a range of polycrystalline YIG samples, pure and rare-earth doped, at 6.0 and 9.2 GHz and at temperatures from room to 150 degrees C. The results are presented in terms of D

A simple hot-pressing system is described which enables small volumes of polycrystalline yttrium iron garnet to be routinely produced. The products have high density, very low second phase content and a controlled grain size. Their magnetic propertie

Measurements are reported of the real part of the magnetic susceptibility, chi ', of polycrystalline YIG at 6 GHz and at room temperature, in magnetic fields outside the spin wave manifold. Above applied fields of about 4000 Oe the simple theory that

The tensor permeability components were determined using circularly polarized microwave radiation, having established maximum allowed sample sizes from a study of the cavity perturbation conditions. It was shown that very slight departures from circu
