      abstract     = {We report the low-temperature properties of phase-pure
                      single crystals of the half-Heusler compound CuMnSb grown by
                      means of optical float zoning. The magnetization, specific
                      heat, electrical resistivity, and Hall effect of our single
                      crystals exhibit an antiferromagnetic transition at TN=55 K
                      and a second anomaly at a temperature T∗≈34 K. Powder
                      and single-crystal neutron diffraction establish an ordered
                      magnetic moment of (3.9±0.1)μB/f.u., consistent with the
                      effective moment inferred from the Curie-Weiss dependence of
                      the susceptibility. Below TN, the Mn sublattice displays
                      commensurate type-II antiferromagnetic order with
                      propagation vectors and magnetic moments along ⟨111⟩
                      (magnetic space group R[I]3c). Surprisingly, below T∗, the
                      moments tilt away from ⟨111⟩ by a finite angle
                      δ≈11∘, forming a canted antiferromagnetic structure
                      without uniform magnetization consistent with magnetic space
                      group C[B]c. Our results establish that type-II
                      antiferromagnetism is not the zero-temperature magnetic
                      ground state of CuMnSb as may be expected of the
                      face-centered cubic Mn sublattice.},
