Acoustic phonon softening and lattice instability driven by on-site - hybridization in CeCoSi
Takeshi Matsumura, Takumi Hasegawa, Ryuma Nakajima +5
Soft phonon modes in tetragonal CeCoSi, which undergoes a structural transition at K followed by antiferromagnetic order at K, have been investigated us…
Distorted triangular skyrmion lattice in a noncentrosymmetric tetragonal magnet
Takeshi Matsumura, Kenshin Kurauchi, Mitsuru Tsukagoshi +6
Magnetic skyrmions are particle-like spin-swirling objects ubiquitously realized in magnets. They are topologically stable chiral kinks composed of multiple modulation waves of spi…
Helicity Selection of the Cycloidal Order in Noncentrosymmetric EuIrGe
Kenshin Kurauchi, Takeshi Matsumura, Mitsuru Tsukagoshi +5
The magnetic helicities of the cycloidal ordering in EuIrGe, with a noncentrosymmetric tetragonal structure, have been studied by circularly polarized resonant X-ray diffractio…
Discovery of antiferromagnetic chiral helical ordered state in trigonal GdNiGa
Shota Nakamura, Takeshi Matsumura, Kazuma Ohashi +5
We have performed magnetic susceptibility, magnetization, and specific heat measurements on a chiral magnet GdNiGa, belonging to the trigonal space group (\#155). A m…
Crystal field excitation in the chiral helimagnet YbNiAl
Mitsuru Tsukagoshi, Suguru Kishida, Kenshin Kurauchi +6
Crystal field level scheme of a uniaxial chiral helimagnet YbNiAl, exhibiting a chiral magnetic soliton lattice state by Cu substitution for Ni, has been determined by inel…
