Lu/Se Substitution Effect on Magnetic Properties of Yb-Based Zigzag Chain Semiconductor YbCuS2
Fumiya Hori, Hiroyasu Matsudaira, Shunsaku Kitagawa +4
We have investigated the changes in the magnetic properties on YbCuS2 by Lu or Se substitutions from a microscopic perspective. In general, it is expected that nonmagnetic Lu subst…
Pressure Evolution of Magnetic Structure and Quasiparticle Excitations in Anisotropic Frustrated Zigzag Chains
Fumiya Hori, Hiroyasu Matsudaira, Shunsaku Kitagawa +3
Frustrated magnetic systems with anisotropic exchange interactions have been recognized as key platforms for discovering exotic quantum states and quasiparticles. In this study, we…
Appearance of -axis magnetic moment in odd-parity antiferromagnetic state in CeRhAs revealed by As-NMR
Shiki Ogata, Shunsaku Kitagawa, Katsuki Kinjo +5
CeRhAs shows the superconducting (SC) multiphase under the -axis magnetic field, which is considered to originate from local inversion symmetry breaking at the Ce site.…
Gapped Spin Excitation in Magnetic Ordered State on Yb-Based Zigzag Chain Compound YbAgSe2
Fumiya Hori, Shunsaku Kitagawa, Kenji Ishida +3
We report the 77Se-nuclear magnetic resonance (NMR) results of trivalent Yb zigzag chain compound YbAgSe2, which is a sister compound of YbCuS2. The 77Se-NMR spectrum was reproduce…
Breakdown of Kubo relation in Pt-Cu nanoparticle
Shunsaku Kitagawa, Yudai Kinoshita, Kenji Ishida +2
Nanoparticles were predicted to exhibit unique physical properties due to quantum size effects, but their identification remains difficult. According to Kubo's theory, the gap size…
Investigation of the hyperfine coupling constant of locally noncentrosymmetric heavy-fermion superconductor CeRhAs
Shiki Ogata, Shunsaku Kitagawa, Katsuki Kinjo +6
We performed As-NMR measurements in to investigate the normal-state magnetic properties of CeRhAs, a recently-discovered heavy-fermion superconductor…
