We measure the cross-correlation between the galaxy density in the DarkEnergy Survey (DES) Science Verification data and the lensing of the cosmicmicrowave background (CMB) as reconstructed with the Planck satellite and theSouth Pole Telescope (SPT). When using the DES main galaxy sample over the fullredshift range $0.2 < z < 1.2$, a cross-correlation signal is detected at $6\sigma$ and $4\sigma$ with SPT and Planck respectively. We then divide the DESgalaxies into five photometric redshift bins, finding significant ($>$$2\sigma$) detections in all bins. Comparing to the fiducial Planck cosmology, wefind the redshift evolution of the signal matches expectations, although theamplitude is consistently lower than predicted across redshift bins. We testfor possible systematics that could affect our result and find no evidence forsignificant contamination. Finally, we demonstrate how these measurements canbe used to constrain the growth of structure across cosmic time. We find thedata are fit by a model in which the amplitude of structure in the $z<1.2$universe is $0.73 \pm 0.16$ times as large as predicted in the LCDM Planckcosmology, a $1.7\sigma$ deviation.
