Abstract

We investigated the magnetization dynamics through the magnetoimpedance effect in an integrated YIG/Pt-stripline system in the frequency range of 0.5 up to 2.0 GHz. Specifically, we explore the dependence of the dynamic magnetic behavior on the field orientation by analyzing beyond the traditional longitudinal magnetoimpedance effect of the transverse and perpendicular setups. We disclose here the strong dependence of the effective damping parameter on the field orientation, as well as verification of the very-low damping parameter values for the longitudinal and transverse configurations. We find considerable sensitivity results, bringing to light the facilities to integrate ferrimagnetic insulators in current and future technological applications.

摘要

我们通过集成YIG/Pt带状线系统中的磁阻抗效应,在0.5至2.0 GHz频率范围内研究了磁化动力学。具体而言,我们通过分析超越传统横向和纵向设置的纵向磁阻抗效应,探讨了动态磁行为对磁场取向的依赖性。我们在此揭示了有效阻尼参数对磁场取向的强烈依赖性,以及对纵向和横向配置的极低阻尼参数值的验证。我们发现了相当显著的灵敏度结果,揭示了在当前和未来技术应用中集成亚铁磁绝缘体的便利性。
