Chiral gauge field in fully spin-polarized magnetic Weyl semimetal with magnetic domain walls

Ozawa, Akihiro*; Araki, Yasufumi; Nomura, Kentaro*

Journal of the Physical Society of Japan, 93(9), p.094704_1 - 094704_9, 2024/09

Modulation of magnetization in magnetic Weyl semimetals leads to the shift of Weyl points in momentum space, which effectively serves as the chirality-dependent gauge field for the Weyl fermions. Here, we theoretically study such a magnetization-induced chiral gauge field, in a fully spin-polarized Weyl ferromagnet Co$$_{3}$$Sn$$_{2}$$S$$_{2}$$. From a tight-binding model of Co$$_{3}$$Sn$$_{2}$$S$$_{2}$$ on stacked kagome lattice with magnetism, we calculate the magnetization-dependent evolution of the Weyl points in momentum space, resulting in the chiral gauge field. In the presence of the magnetic domain wall structure, we evaluate the chiral magnetic field arising from the spatial profile of the chiral gauge field. We find that a magnetic domain wall in Co$$_{3}$$Sn$$_{2}$$S$$_{2}$$ gives rise to a giant chiral magnetic field for the Weyl fermions, which reaches the order of a few hundred tesla to induce the Landau quantization. Such a giant chiral magnetic field may also influence the novel transport phenomena, such as the charge pumping by the domain wall motion, compatible with the spinmotive force.

What makes black lacquer black?; The Cutting edge of traditional lacuqer technology from Jomon Period in Japan

Nankawa, Takuya

Kagaku, 79(8), p.48 - 52, 2024/08

Lacquer is a natural paint with excellent water and chemical resistance. It has long been known that adding a very small amount of iron into raw lacquer produces a very beautiful black color called Shikoku. However, the structure and reactions of lacquer are still largely unknown, and the reason of black color is also unclear. In this study, we analyzed the structure of raw lacquer and black lacquer films by using different kind of quantum beams. As a result, black lacquer has a completely different nanostructure from raw lacquer, and that the color changes depending on the difference in the structure. This result is the first successful analysis of the structure of the lacquer film, which had been a mystery for many years. This commentary describes this research and also explains how this research has been proceeded.

Quantum metric and Berry curvature are two fundamental and distinct factors to describe the geometry of quantum eigenstates. While Berry curvature is known for playing crucial roles in several condensed-matter states, quantum metric, which was predicted to induce new classes of topological phenomena, has rarely been touched, particularly in an ambient circumstance. Using a topological chiral antiferromagnet Mn$$_{3}$$Sn adjacent to Pt, at room temperature, we successfully manipulate the quantum-metric structure of electronic states through its interplay with the nanoscale spin texture at the Mn$$_{3}$$Sn/Pt interface. This is manifested by a time-reversal-odd second-order Hall effect that is robust against extrinsic electron scattering, in contrast to any transport effects from the Berry curvature. We also verify the flexibility of controlling the quantum-metric structure, as the interacting spin texture can be tuned by moderate magnetic fields or by interface engineering via spin-orbit interactions. Our work paves a way for harnessing the quantum-metric structure to unveil emerging topological physics in practical environments and to build applicable nonlinear devices.
