  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. SrRuO3 is a promising candidate
among TMOs due to its large and tunable SOT-efficiency as well as high
conductivity and chemical stability. However, a further study for benchmarking
the SOT-efficiency and realizing SOT-driven magnetization switching in SrRuO3
is still highly desired so far. Here, we systematically study the SOT
properties of high-quality SrRuO3 thin film heterostructuring with different
magnetic alloys of both IMA and PMA configuration by the harmonic Hall voltage
technique. Our results indicate that SrRuO3 possesses pronounced SOT-efficiency
of about 0.2 at room temperature regardless of the magnetic alloys, which is
comparable to typical heavy metals (HMs). Furthermore, we achieve SOT-driven
magnetization switching with a low threshold current density of 3.8x10^10
A/m^2, demonstrating the promising potential of SrRuO3 for practical devices.
By making a comprehensive comparison with HMs, our work unambiguously
benchmarks the SOT properties and concludes the advantages of SrRuO3, which may
bring more diverse choices for SOT applications by utilizing hybrid-oxide/metal
and all-oxide systems.
