摘要

我们研究了室温下具有垂直磁各向异性的铁磁性 Pt/GdFeCo/SiN 和 Rh/GdFeCo/SiN 线中由自旋轨道力矩和 Dzyaloshinskii-Moriya 相互作用(DMI)驱动的电流诱导畴壁运动(CIDWM)。我们发现,与 Rh/GdFeCo 金属丝相比,Pt/GdFeCo 金属丝中的 CIDWM 临界电流密度小了近两倍,而 DW 迁移率则大了约四倍。通过测量纵向面内磁场下的 CIDWM,可以估算出两种金属丝的 DMI 常数 (D)。Pt/GdFeCo 金属丝的 D 估计值约为 Rh/GdFeCo 金属丝的七倍。这表明铂/钆铁钴金属丝的 CIDWM 效率要高得多,这主要归因于铂/钆铁钴金属丝的 DMI 大得多,而 DMI 大得多的原因可能是铂/钆铁钴金属丝的重金属/铁磁体界面杂化明显更强。

Current-induced domain wall motion driven by spin–orbit torque and Dzyaloshinskii–Moriya interaction in Pt/GdFeCo and Rh/GdFeCo wires
We investigated current-induced domain wall motion (CIDWM) driven by spin–orbit torque and Dzyaloshinskii–Moriya interaction (DMI) in ferrimagnetic Pt/GdFeCo/SiN and Rh/GdFeCo/SiN wires with perpendicular magnetic anisotropy at room temperature. We found that CIDWM in the Pt/GdFeCo wire exhibits nearly two times smaller in critical current density and about four times larger in DW mobility compared to the Rh/GdFeCo wire. By measuring the CIDWM under a longitudinal in-plane magnetic field, the DMI constant (D) was estimated for both wires. The estimated value of D for the Pt/GdFeCo wire is approximately seven times larger than the Rh/GdFeCo wire. It indicated that the Pt/GdFeCo wire revealed the CIDWM with much higher efficiency, mainly attributed to the much larger DMI, which may come from significantly stronger interfacial heavy metal/ferrimagnet hybridization in the Pt/GdFeCo wire.

期刊介绍: AIP Advances is an open access journal publishing in all areas of physical sciences—applied, theoretical, and experimental. All published articles are freely available to read, download, and share. The journal prides itself on the belief that all good science is important and relevant. Our inclusive scope and publication standards make it an essential outlet for scientists in the physical sciences. AIP Advances is a community-based journal, with a fast production cycle. The quick publication process and open-access model allows us to quickly distribute new scientific concepts. Our Editors, assisted by peer review, determine whether a manuscript is technically correct and original. After publication, the readership evaluates whether a manuscript is timely, relevant, or significant.
