Local probe investigation of the spin dynamics in the kagome and inter-layers of orthorhombic barlowite Cu${}_4$(OD)${}_6$FBr: ${}^{79}$Br and ${}^{63}$Cu NQR study

Takashi Imai, Jiaming Wang, Rebecca W. Smaha +3

We report ${}^{79}$Br and ${}^{63}$Cu nuclear quadrupole resonance (NQR) in the paramagnetic state above $T_{\text{N}}=15$ K of the antiferromagnetic orthorhombic phase of barlowite Cu…
