Abstract
We report $^{51}$V NMR, $\mu$SR and zero applied field $^{63,65}$Cu NMR
measurements on powder samples of Sr-vesignieite, SrCu$_3$V$_2$O$_8$(OH)$_2$, a
$S = 1/2$ nearly-kagome Heisenberg antiferromagnet. Our results demonstrate
that the ground state is a $\mathbf{q} = 0$ magnetic structure with spins
canting either in or out of the kagome plane, giving rise to weak
ferromagnetism. We determine the size of ordered moments and the angle of
canting for different possible $\mathbf{q} = 0$ structures and orbital
scenarios, thereby providing insight into the role of the Dzyaloshinskii-Moriya
(DM) interaction in this material.
