چکیده
Spin-orbit torques (SOTs) from transition metal oxides (TMOs) in conjunction with magnetic materials have recently attracted tremendous attention for realizing high-efficient spintronic devices. ${\mathrm{SrRuO}}_{3}$ is a promising candidate among TMOs due to its large and tunable SOT efficiency as well high conductivity chemical stability. However, further study benchmarking the SOT-driven magnetization switching still highly desired so far. Here, we systematically properties of high-quality thin film heterostructuring different alloys both IMA PMA configuration by harmonic Hall voltage technique. Our results indicate that possesses pronounced about 0.2 at room temperature regardless alloys, which comparable typical heavy metals (HMs). Furthermore, achieve low threshold current density $3.8\ifmmode\times\else\texttimes\fi{}{10}^{10}\phantom{\rule{0.28em}{0ex}}\mathrm{A}/{\mathrm{m}}^{2}$, demonstrating potential practical By making comprehensive comparison HMs, our work unambiguously benchmarks concludes advantages ${\mathrm{SrRuO}}_{3}$, may bring more diverse choices applications utilizing hybrid-oxide/metal all-oxide systems.

Room-Temperature Spin-Orbit Torque Switching Induced by a Topological Insulator.
The strongly spin-momentum coupled electronic states in topological insulators (TI) have been extensively pursued to realize efficient magnetic switching. However, previous studies show a large discrepancy of the charge-spin conversion efficiency. Moreover, current-induced magnetic switching with TI can only be observed at cryogenic temperatures. We report spin-orbit torque switching in a TI-fe...

Magnetization dynamics symmetry plays important roles in magnetization switching. Here we study magnetic field and spin torque induced magnetization switching. Spin moment transferring from polarized itinerant electrons to local magnetization provides a magnetization switching mechanism without using external magnetic field. Besides its importance in fundamental magnetization switching dynamics...

Spin-orbit torque (SOT)-induced magnetization switching shows promise for realizing ultrafast and reliable spintronics devices. Bipolar switching of the perpendicular magnetization by the SOT is achieved under an in-plane magnetic field collinear with an applied current. Typical structures studied so far comprise a nonmagnet/ferromagnet (NM/FM) bilayer, where the spin Hall effect in the NM is r...
