Raman Spectroscopic Investigation of Ferroaxial Order in Na2BaNi(PO4)2 Single Crystals
Ryunosuke Takahashi, Hayato Seno, Marin Takahashi +9
Ferroaxial order is characterized by the breaking of mirror symmetry parallel to the crystallographic principal axis, which often originates from spontaneous rotational distortions…

Synthesis, crystal and electronic structures, and second harmonic generation of La 4Ge 3S12
Hiroya Ohtsuki, Suguru Nakata, Yu Yamane +3
The crystal structure of La 4 Ge 3S 12 has been known to be noncentrosymmetric for almost four decades. This characteristic inversion symmetry breaking suggests the presence of non…

All-optical helicity-dependent switching in NiCoO thin films
Ryunosuke Takahashi, Yann Le Guen, Suguru Nakata +8
All-optical switching (AOS) involves manipulating magnetization using only pulsed laser, presenting a promising approach for next-generation magnetic recording devices. NiCo2O4 (NC…
