In transition-metal compounds, the transition-metal d electrons play an important role in their physical properties; however, the effects of the electron correlation between the ligand p electrons have not been clear yet. In this Letter, the Ru 4d an

SrRuO3 under tensile strain: Thickness-dependent electronic and magnetic properties

Autor: Wakabayashi, Yuki K., Kobayashi, Masaki, Seki, Yuichi, Yamagami, Kohei, Takeda, Takahito, Ohkochi, Takuo, Taniyasu, Yoshitaka, Krockenberger, Yoshiharu, Yamamoto, Hideki

The burgeoning fields of spintronics and topological electronics require materials possessing a unique combination of properties: ferromagnetism, metallicity, and chemical stability. SrRuO3 (SRO) stands out as a compelling candidate due to its except

Allotropic transition of Dirac semimetal {\alpha}-Sn to superconductor {\beta}-Sn induced by irradiation of focused ion beam

Autor: Inagaki, Kohdai, Ishihara, Keita, Hotta, Tomoki, Seki, Yuichi, Takeda, Takahito, Ishida, Tatsuhiro, Ootsuki, Daiki, Kawasaki, Ikuto, Fujimori, Shin-ichi, Tanaka, Masaaki, Anh, Le Duc, Kobayashi, Masaki

Diamond-type structure allotrope {\alpha}-Sn is attracting much attention as a topological Dirac semimetal (TDS). In this study, we demonstrate that {\alpha}-Sn undergoes a phase transition to another allotrope {\beta}-Sn with superconductivity at lo

Magnetic anisotropy driven by ligand in 4d transition metal oxide SrRuO3

Autor: Wakabayashi, Yuki K., Kobayashi, Masaki, Seki, Yuichi, Kotani, Yoshinori, Ohkochi, Takuo, Yamagami, Kohei, Kitamura, Miho, Taniyasu, Yoshitaka, Krockenberger, Yoshiharu, Yamamoto, Hideki

The origin of magnetic anisotropy in magnetic compounds is a longstanding issue in solid state physics and nonmagnetic ligand ions are considered to contribute little to magnetic anisotropy. Here, we introduce the concept of ligand driven magnetic an
