 Abstract: We report the growth of CuMnSb thin films by molecular beam epitaxy on InAs (001) substrates. The CuMnSb layers are compressively strained (0.6 %) due to lattice mismatch. The thin films have a CO full width at halfmaximum of 7.7 arcsec according to high resolution x-ray diffraction, and a root-mean-square roughness of 0.14 nm as determined by atomic force microscopy. Magnetic and electrical properties are found to be consistent with reported values from bulk samples. We find a Neel temperature of 62 K, a Curie-Weiss temperature of -65 K, and an effective moment of 5.9 mu B/f.u. Transport measurements confirm the antiferromagnetic transition and show a residual resistivity at 4 K of 35 mu Omega cm.
