Investigation of the magnetism of ${\mathrm{Cu}}_{3}{\mathrm{Mo}}_{2}{\mathrm{O}}_{9}$ single crystal, which has antiferromagnetic (AF) linear chains interacting with AF dimers, reveals an AF second-order phase transition at ${T}_{N}=7.9\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. Although weak-ferromagnetic-like behavior appears at lower temperatures in low magnetic fields, complete remanent magnetization cannot be detected down to $0.5\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. However, a jump is… Expand
