	abstract = {Mn5Ge3Cx films with x >= 0.5 were experimentally shown to exhibit a strongly enhanced Curie temperature T-C compared to Mn5Ge3. In this letter we present the results of our first principles calculations within Green{\textquoteright}s function approach, focusing on the effect of carbon doping on the electronic and magnetic properties of the Mn5Ge3. The calculated exchange coupling constants revealed an enhancement of the ferromagnetic Mn-Mn interactions mediated by carbon. The essentially increased T-C in Mn5Ge3C is well reproduced in our Monte Carlo simulations and together with the decrease of the total magnetization is found to be predominantly of an electronic nature.},
