Incommensurate quantum magnet based on 4f-electron in a zigzag spin-1/2 chain of YbCuS
T. Onimaru, Y. Ohmagari, S. Mizutani +8
We performed high-resolution powder neutron diffraction experiments and discovered an elliptic helical incommensurate magnetic structure in the semiconducting rare-earth magnet YbC…

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…

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…
