Sub-micron YIG microstructure and ferromagnetic resonance linewidth

It has been shown possible to push the grain size of sintered YIG below 1 micron by using 400Å YIG microcrystals and pressure sintering. This has implications for moving up the threshold for nonlinear spinwave excitation with a microwave pump. The ferromagnetic resonance linewidth has been shown to...

Description
Summary:It has been shown possible to push the grain size of sintered YIG below 1 micron by using 400Å YIG microcrystals and pressure sintering. This has implications for moving up the threshold for nonlinear spinwave excitation with a microwave pump. The ferromagnetic resonance linewidth has been shown to be inversely dependent on grain size on a log-log scale.
