    This paper describes the evaluation of magnetization dynamics in YIG polycrystalline films with various thicknesses using our proposed measurement technique. The saturation magnetostriction ( λs) are approximately less than −1.0×10−6 regardless of the film thickness and are lower than that of bulk polycrystalline YIG, which might be attributed to the structural and/or magnetic inhomogeneities. On the other hand, the in-plane effective damping constant ( αeff) decreases approximately from 0.00384±0.00029 to 0.00316±0.00013 with the increase of film thickness, and their values are much higher than those of nano-meter thick and micro-meter thick YIG films deposited on GGG substrates. The reason for this difference may be that the extrinsic damping originating from the magnetic inhomogeneities are enhanced in the film plane. In addition, αeff slightly increases as λs decreases. This tendency is opposite to those of Ni-Fe and Fe-Si polycrystalline films, and the correlation between αeff and λs does not appear. Therefore, these results suggest that magnetic inhomogeneities are mainly influenced to both αeff and λs in the film plane.

  5. Effect of oxygen incorporation on dynamic magnetic properties in Ta-O/Co-Fe-B bilayer films under out-of-plane and in-plane magnetic fields

    Dynamic magnetic properties of Ta-O/Co20Fe60B20 bilayer films are strongly influenced by the oxidation condition of the Ta-O layer. The oxidation of the Ta-O layer by a slight amount of oxygen with a pressure ( POxygen) of 0.03 Pa decreases in-plane damping constant ( αIP), and increases the effective magnetization (4π Ms,eff). Then, both αIP and 4π Ms,eff maintain their values by increasing POxygen up to 0.3 Pa. The out-of-plane damping constant ( αOP) showed a similar tendency to that of αIP against POxygen, although αOP is much smaller than αIP in every POxygen. αOP reaches to 0.0033 for sample oxidized at 0.03 Pa. It was suggested that αIP consists of both the intrinsic damping and the extrinsic damping, while αOP is closer to the intrinsic damping. The control of αOP and αIP by the oxidation would be beneficial in designing the high frequency spintronic devices.
