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…
Widely-sweeping magnetic field-temperature phase diagrams for skyrmion-hosting centrosymmetric tetragonal magnets
Satoru Hayami, Yasuyuki Kato
We numerically investigate the stabilization mechanisms of skyrmion crystals under thermal fluctuations and external magnetic field in itinerant centrosymmetric tetragonal magnets.…
