Odd-Parity Multipoles by Staggered Magnetic Dipole and Electric Quadrupole Orderings in CeCoSi
Megumi Yatsushiro, Satoru Hayami
We investigate a possibility of odd-parity multipole orderings in a locally noncentrosymmetric tetragonal compound CeCoSi. By performing symmetrical and microscopic mean-field anal…
Double- Chiral Stripe in the - Model with Strong Spin-Charge Coupling
Ryota Yambe, Satoru Hayami
We investigate the stability of multiple- spiral states in - electron systems with the strong spin-charge coupling. By using variational calculations on a square lattice,…
Tracing Monopoles and Anti-monopoles in a Magnetic Hedgehog Lattice
Shun Okumura, Satoru Hayami, Yasuyuki Kato +1
The magnetic hedgehog lattice (HL), which was recently discovered in the 20-type chiral magnet MnSiGe, is a topological spin texture with a periodic array of magneti…
Momentum-Dependent Spin Splitting by Collinear Antiferromagnetic Ordering
Satoru Hayami, Yuki Yanagi, Hiroaki Kusunose
We clarify the macroscopic symmetry and microscopic model-parameter conditions for emergence of spin-split electronic band structure in collinear antiferromagnets without atomic sp…
Magnetic hedgehog lattices in noncentrosymmetric metals
Shun Okumura, Satoru Hayami, Yasuyuki Kato +1
The magnetic hedgehog lattice (HL) is a noncoplanar magnetic texture with a periodic array of magnetic monopoles and anti-monopoles. Despite phenomenological and numerical studies…
Magnetic Vortex induced by Nonmagnetic Impurity in Ferromagnets: Magnetic Multipole and Toroidal around the Vacancy
Satoru Hayami, Hiroaki Kusunose, Yukitoshi Motome
We report our theoretical study on nucleation of a magnetic vortex around a nonmagnetic impurity doped into ferromagnets. The mechanism lies in the asymmetric Dzyaloshinskii-Moriya…
