We cross-correlate galaxy weak lensing measurements from the Dark Energy Survey (DES) year-one data with a cosmic microwave background (CMB) weak lensing map derived from South Pole Telescope (SPT) and Planck data, with an effective overlapping area of 1289-deg². With the combined measurements from four source galaxy redshift bins, we obtain a detection significance of 5.8σ. We fit the amplitude of the correlation functions while fixing the cosmological parameters to a fiducial ΛCDM model, finding A=0.99±0.17. We also use the correlation function measurements to constrain shear calibration bias, obtaining constraints that are consistent with previous DES analyses. Lastly, when performing a cosmological analysis under the ΛCDM model, we obtain the marginalized constraints of Ω_m= 0.261$$^{+0.070}_{-0.051}$$ and S8≡σ₈ $$\sqrt{Ω_m/0.3}$$=0.660$$^{+0.085}_{-0.100}$$. These measurements are used in a companion work that presents cosmological constraints from the joint analysis of two-point functions among galaxies, galaxy shears, and CMB lensing using DES, SPT, and Planck data.
