Abstract :
Films of yttrium--iron garnet have been grown on gadolinium-gallium-garnet substrates by liquid-phase epitaxy with thickness up to 100 μm. Measurements by the bandstop-filter technique in the frequency range 2--8 GHz have shown resonance line-widths as low as 20 A/m(0.25 Oe). These results are compared with measurements of linewidth by the cavity-resonance technique at 9.5 GHz.
