In the metallic pyrochlore ${\mathrm{Nd}}_{2}{\mathrm{Mo}}_{2}{\mathrm{O}}_{7}$, conducting molybdenum sublattice adopts canted, yet nearly collinear, ferromagnetic order with nonzero scalar spin chirality. The chemical potential may be controlled by replacing ${\mathrm{Nd}}^{3+}$ ${\mathrm{Ca}}^{2+}$, while introducing only minimal additional disorder to states. Here, we demonstrate stability ...
