Abstract
Neutron diffraction and nuclear magnetic resonance (NMR) measurements have been used to analyze the magnetic structure in the $S=\frac{1}{2}$ kagome antiferromagnet ${\mathrm{CdCu}}_3{\left(\mathrm{OH}\right)}_6{\left({}_3\right)}_2\cdot H_{2}O$. Below the magnetic ordering temperature $T_{\text{N}}\simeq 4K$, magnetic Bragg reflections at (101) and (100) were found in the neutron diffraction pattern, which suggests a $q=0$ magnetic structure. Furthermore, the vector spin chirality for…..
