Dynamics of Topological Defects in Type-II Superconductors under Gradients of Temperature/Spin Density
Takuma Kanakubo, Hiroto Adachi, Masanori Ichioka +1
We theoretically investigate the motion of a domain wall and a vortex in type-II superconductors driven by inhomogeneities of temperature or spin accumulation. The model consists o…
Ginzburg-Landau theory of spin pumping through an antiferromagnetic layer near the Néel temperature
Yuto Furutani, Hayato Fukushima, Yutaka Yamamoto +2
Spin pumping is a microwave-driven means for injecting spins from a ferromagnet into the adjacent target material. The insertion of a thin antiferromagnetic layer between the ferro…
Spin Seebeck effect in two-sublattice ferrimagnets in the vicinity of
Hayato Fukushima, Masanori Ichioka, Hiroto Adachi
Spin Seebeck effect refers to the magnonic thermal spin injection from a magnet into the adjacent heavy metal. A ferrimagnetic insulator yttrium iron garnet (YIG) is the material m…
Fractional vortex array realized at twin boundary in a nematic superconductor
Sakiko Noda, Hiroto Adachi, Masanori Ichioka
Within a framework of two-component Ginzburg-Landau theory as a model of superconducting FeSe, we study the spatial structure of vortex states in the presence of nematic twin bound…
