Bi-substituted LPE garnet films with FMR linewidth as small as YIG
Description
This paper reports highly Bi-substituted LPE garnet films, Bi0.85Lu2.15FE5O12 and Fi1.4Y1.6Fe5O12, with FMR linewidths as small as that of YIG, grown using only Bi2O3 as a flux. Substitution of Al for FE causes a sharp increase in ΔH. The minimum values of ΔH obtained were 1.5 Oe for Bi0.85Lu2.15Fe5O12 films and 0.73 Oe for Bi1.45Y1.6Fe5O12 films, which are the smallest values reported to date for such heavily Bi-substituted garnet films. This may be ascribed to the fact that no Pb was included in the films. It was experimentally verified that MSSW propagation is possible for Bi0.85Lu2.15Fe5O12 films. These films are very promising for MSW-based optical waveguide devices, since they have a specific Faraday rotation ten times larger than that of YIG, as well as a very small optical absorption coefficient at a wavelength of 1.3 μm
