Incommensurate modulation with $Q=0$ A-type Antiferromagnetic Order in CeRh${}_2$As${}_2$ revealed by NQR studies

Shiki Ogata, Shunsaku Kitagawa, Kenji Ishida +4

We performed ${}^{75}$As nuclear quadrupole resonance (NQR) and nuclear magnetic resonance (NMR) measurements on a higher-quality single-crystalline CeRh${}_2$As${}_2$, a heavy-fermion s…
