Universal dynamics of magnetic monopoles in two-dimensional kagomé ice
Hiroshi Takatsu, Kazuki Goto, Hiromi Otsuka +8
A magnetic monopole in spin ice is a novel quasiparticle excitation in condensed matter physics, and we found that the ac frequency dependent magnetic susceptibility in the…
Combinatorial tuning of electronic structure and thermoelectric properties in CoMnAlSi Weyl semimetals
Rajkumar Modak, Kazuki Goto, Shigenori Ueda +3
A tuning of Fermi level (E) near Weyl points is one of the promising approaches to realize large anomalous Nernst effect (ANE). In this work, we introduce an efficient approach…
Visualizing half-metallic bulk band structure with multiple Weyl cones of the Heusler ferromagnet
Takashi Kono, Masaaki Kakoki, Tomoki Yoshikawa +5
Using a well-focused soft X-ray synchrotron radiation beam, angle-resolved photoelectron spectroscopy was applied to a full-Heusler-type CoMnGe alloy to elucidate its bulk band…
Spin-polarized Weyl cones and gigantic anomalous Nernst effect in ferromagnetic Heusler films
Kazuki Sumida, Yuya Sakuraba, Keisuke Masuda +8
Weyl semimetals are characterized by the presence of massless band dispersion in momentum space. When a Weyl semimetal meets magnetism, large anomalous transport properties emerge…
Comparative studies of low temperature X-ray diffraction experiments on R2Ir2O7 (R = Nd, Eu, and Pr)
Hiroshi Takatsu, Kunihiko Watanabe, Kazuki Goto +1
The cubic symmetry of pyrochlore iridium oxides R2Ir2O7 (R = Nd, Eu, and Pr) has been investigated by high resolution X-ray diffraction experiments down to 4 K,in order to clarify…
A Scaling Theory for ac Magnetic Response in Kagome Ice
Hiromi Otsuka, Hiroshi Takatsu, Kazuki Goto +1
A theory for frequency-dependent magnetic susceptibility χ(ω) is developed for thermally activated magnetic monopoles in kagome ice. By mapping this system to a two-dimensional (2D…
AC Susceptibility of the Dipolar Spin Ice Dy2Ti2O7: Experiments and Monte Carlo Simulations
Hiroshi Takatsu, Kazuki Goto, Hiromi Otsuka +4
Experimental data of the frequency-dependent ac susceptibility for the dipolar spin ice Dy2Ti2O7 has been analyzed by Monte Carlo simulations on the basis of the single-spin-flip M…
Long-range order and spin-liquid states of polycrystalline TbTiO
T. Taniguchi, H. Kadowaki, H. Takatsu +11
Low-temperature states of polycrystalline samples of a frustrated pyrochlore oxide TbTiO have been investigated by specific heat, magnetic susceptibility, a…
Evolution of two-step structural phase transition in Fe1+dTe detected by low-temperature x-ray diffraction
Yoshikazu Mizuguchi, Kentaro Hamada, Kazuki Goto +3
The low-temperature crystal structure of Fe1.13Te, which exhibits an anomalous two-step magnetic transition, was clarified by the systematic x-ray diffraction measurements. It was…
Absence of anomalous negative lattice-expansion for polycrystalline sample of Tb2Ti2O7
Kazuki Goto, Hiroshi Takatsu, Tomohiro Taniguchi +1
High resolution X-ray powder-diffraction experiments on a well-characterized polycrystalline sample of the spin liquid Tb2Ti2O7 reveal that it shows normal positive thermal-expansi…
