Stoichiometric growth of SrTiO3 films via Bayesian optimization with adaptive prior mean
Yuki K. Wakabayashi, Takuma Otsuka, Yoshiharu Krockenberger +3
Perovskite insulator SrTiO3 is expected to be applied to the next generation of electronic and photonic devices as high-k capacitors and photocatalysts. However, reproducible growt…
Scattering-dependent transport of SrRuO3 films: From Weyl fermion transport to hump-like Hall effect anomaly
Shingo Kaneta-Takada, Yuki K. Wakabayashi, Yoshiharu Krockenberger +5
Recent observation of quantum transport phenomena of Weyl fermions has brought much attention to 4d ferromagnetic perovskite SrRuO3 as a magnetic Weyl semimetal. Besides, the hump-…
Isotropic orbital magnetic moments in magnetically anisotropic SrRuO3 films
Yuki K. Wakabayashi, Masaki Kobayashi, Yukiharu Takeda +6
Epitaxially strained SrRuO3 films have been a model system for understanding the magnetic anisotropy in metallic oxides. In this paper, we investigate the anisotropy of the Ru 4d a…
Bayesian optimization with experimental failure for high-throughput materials growth
Yuki K. Wakabayashi, Takuma Otsuka, Yoshiharu Krockenberger +3
A crucial problem in achieving innovative high-throughput materials growth with machine learning and automation techniques, such as Bayesian optimization (BO) and robotic experimen…
Superconductivity in infinite-layer CaCuO2-brownmillerite Ca2Fe2O5 superlattices
Ai Ikeda, Yoshiharu Krockenberger, Yoshitaka Taniyasu +1
High-temperature cuprate superconductors have naturally a superlattice structure. Infinite-layer CaCuO2 is the common ingredient of cuprates with superconducting transition tempera…
Single-domain perpendicular magnetization induced by the coherent O 2p-Ru 4d hybridized state in an ultra-high-quality SrRuO3 film
Yuki K. Wakabayashi, Masaki Kobayashi, Yukiharu Takeda +8
We investigated the Ru 4d and O 2p electronic structure and magnetic properties of an ultra-high-quality SrRuO3 film on SrTiO3 grown by machine-learning-assisted molecular beam epi…
