Room-Temperature Polarity Control of the Anomalous Nernst Effect in a High-Magnetic-Anisotropy Topological Nodal-Line MnAlGe
Nanhe Kumar Gupta, Keisuke Masudaa, Masaaki Kakoki +7
Controlling the polarity of anomalous Nernst thermopower is a promising strategy for enhancing the performances of thermoelectric applications. However, realizing such control at r…
Laser-based angle-resolved photoemission spectroscopy with micrometer spatial resolution and detection of three-dimensional spin vector
Takuma Iwata, T. Kousa, Y. Nishioka +11
We have developed a state-of-the-art apparatus for laser-based spin- and angle-resolved photoemission spectroscopy with micrometer spatial resolution (micro-SARPES). This equipment…
Ultrafast electron dynamics in a topological surface state observed in two-dimensional momentum space
J. Reimann, K. Sumida, M. Kakoki +5
We study ultrafast population dynamics in the topological surface state of SbTe in two-dimensional momentum space with time- and angle-resolved two-photon photoemission. Li…
Visualizing half-metallic bulk band structure with multiple Weyl cones of the Heusler ferromagnet
Takashi Kono, Masaaki Kakoki, Tomoki Yoshikawa +5
Using a well-focused soft X-ray synchrotron radiation beam, angle-resolved photoelectron spectroscopy was applied to a full-Heusler-type CoMnGe alloy to elucidate its bulk band…
Spin-polarized Weyl cones and gigantic anomalous Nernst effect in ferromagnetic Heusler films
Kazuki Sumida, Yuya Sakuraba, Keisuke Masuda +8
Weyl semimetals are characterized by the presence of massless band dispersion in momentum space. When a Weyl semimetal meets magnetism, large anomalous transport properties emerge…
