  We study the spin ordering of a quantum dot defined via magnetic barriers in
an interacting quantum spin Hall edge. The spin-resolved density-density
correlation functions are computed. We show that strong electron interactions
induce a ground state with a highly correlated spin pattern. The crossover from
the liquid-type correlations at weak interactions to the ground state spin
texture found at strong interactions parallels the formation of a
one-dimensional Wigner molecule in an ordinary strongly interacting quantum
dot.
