Abstract
Effects of the electron doping on the magnetic and electronic properties have been investigated in the conducting double perovskite ${\mathrm{Sr}}_{2}{\mathrm{FeMoO}}_{6}.$ Judging from the enhanced moment ${\ensuremath{\mu}}_{\mathrm{Mo}}$ at the Mo site, the doped electrons are considered to occupy mainly the down-spin $\mathrm{Mo}4d$ band. Filling dependence of the saturation magnetization ${M}_{\mathrm{s}},$ the spin-wave stiffness coefficient ${D}_{\mathrm{s}}$ and the $\ensuremath{\gamma}$ coefficient are discussed on the basis of a $\mathrm{LDA}+U$ band calculation. We further discuss possible origins for the magnetism.
