Discovery of antiferromagnetic chiral helical ordered state in trigonal GdNi${}_3$Ga${}_9$

Shota Nakamura, Takeshi Matsumura, Kazuma Ohashi +5

We have performed magnetic susceptibility, magnetization, and specific heat measurements on a chiral magnet GdNi${}_3$Ga${}_9$, belonging to the trigonal space group $R32$ (\#155). A m…
