Emergent electric field from magnetic resonances in a one-dimensional chiral magnet

Kotaro Shimizu, Shun Okumura, Yasuyuki Kato +1

The emergent electric field (EEF) is a fictitious electric field acting on conduction electrons through the Berry phase mechanism. The EEF is generated by the dynamics of noncollin…

High-field phase diagram of the chiral-lattice antiferromagnet Sr(TiO)Cu4(PO4)4

Toshihiro Nomura, Yasuyuki Kato, Yukitoshi Motome +9

High-field phase diagram of a chiral-lattice antiferromagnet Sr(TiO)Cu4(PO4)4 is studied by means of the ultrasound, dielectric, and magnetocaloric-effect measurements. These exper…

Magnetic bubble crystal in tetragonal magnets

Satoru Hayami, Yasuyuki Kato

A magnetic bubble crystal is a two-dimensional soliton lattice consisting of multiple spin density waves similar to a magnetic skyrmion crystal. Nevertheless, the emergence of the…

Ground-State Phase Diagram of the Kitaev-Heisenberg Model on a Three-dimensional Hyperhoneycomb Lattice

Kiyu Fukui, Yasuyuki Kato, Yukitoshi Motome

The Kitaev model, which hosts a quantum spin liquid (QSL) in the ground state, was originally defined on a two-dimensional honeycomb lattice, but can be straightforwardly extended…

Magnetic, transport and topological properties of Co-based shandite thin films

Kazuki Nakazawa, Yasuyuki Kato, Yukitoshi Motome

The kagome ferromagnet, Co-based shandite Co3Sn2S2, shows a large anomalous Hall effect (AHE) associated with the Weyl nodes. A thin film with a Co kagome monolayer was predicted t…

Hidden Topological Transitions in Emergent Magnetic Monopole Lattices

Yasuyuki Kato, Yukitoshi Motome

Topological defects, called magnetic hedgehogs, realize emergent magnetic monopoles, which are not allowed in the ordinary electromagnetism described by Maxwell's equations. Such m…
