Abstract
Nonmagnetic second-phase inclusions of two different average sizes (2.5 ± 0.5 and 1.2 ± 0.5 μ m) were produced in specimens of polycrystalline YIG. A dependence of spin-wave linewidth on inclusion size was observed. The linear relationship between spin-wave linewidth and the concentration of second-phase inclusions was dependent on the wave vector k. At k ≈ 2 × 105 cm−1, the relationship was 0.15 Oe and 0.075 Oe per % second-phase concentration for the samples with the smaller and larger inclusions, respectively. It is suggested that in porous specimens the average size of the pores may affect the spin-wave linewidth and that this effect is similar to the transit-time effect produced by finite grain sizes.
