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.}, cin = {JCNS-FRM-II / JCNS-2 / MLZ}, ddc = {530}, cid = {I:(DE-Juel1)JCNS-FRM-II-20110218 / I:(DE-Juel1)JCNS-2-20110106 / I:(DE-588b)4597118-3}, pnm = {6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623) / 6G15 - FRM II / MLZ (POF3-6G15)}, pid = {G:(DE-HGF)POF3-6G4 / G:(DE-HGF)POF3-6G15}, experiment = {EXP:(DE-MLZ)HEIDI-20140101 / EXP:(DE-MLZ)MIRA-20140101 / EXP:(DE-MLZ)RESI-20140101 / EXP:(DE-MLZ)SPODI-20140101 / EXP:(DE-MLZ)DNS-20140101}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000433044400001}, doi = {10.1103/PhysRevMaterials.2.054413}, url = {https://juser.fz-juelich.de/record/859488}, }
