We present a new way to construct de Sitter vacua in type IIB fluxcompactifications, in which moduli stabilization and D-term uplifting can becombined in a manner consistent with the supergravity constraints. Here, theclosed string fluxes fix the dilaton and the complex structure moduli whileperturbative quantum corrections to the Kahler potential stabilize the volumeKahler modulus in an AdS_4-vacuum. Then, the presence of magnetized D7-branesin this setup provide supersymmetric D-terms in a fully consistent way whichuplift the AdS_4-vacuum to a metastable dS-minimum.Comment: 1+14 pages, 1 figure, LaTeX, v2: uses JHEP class, references added, typos removed, matches published version (JHEP
