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…
Thermodynamic approach for enhancing superconducting critical current performance
Masashi Miura, Go Tsuchiya, Takumu Harada +14
The addition of artificial pinning centers has led to an impressive increase in critical current density () in a superconductor, enabling record-breaking all-superconduc…
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.…
Ground-state phase diagram of spin- Kitaev-Heisenberg models
Kiyu Fukui, Yasuyuki Kato, Joji Nasu +1
The Kitaev model, whose ground state is a quantum spin liquid (QSL), was originally conceived for spin moments on a honeycomb lattice. In recent years, the model has been e…
Magnetic Hedgehog Lattice in a Centrosymmetric Cubic Metal
Shun Okumura, Satoru Hayami, Yasuyuki Kato +1
The hedgehog lattice (HL) is a three-dimensional topological spin texture hosting a periodic array of magnetic monopoles and antimonopoles. It has been studied theoretically for no…
