${\mathrm{W}}_{\text{0.75}}{\mathrm{Re}}_{\text{0.25}}$, in its bulk form, is an interesting superconducting material due to its multiple crystalline phases, each exhibiting distinct superconducting characteristics. However, little is known about how these phases manifest in thin-film form, where deposition conditions and dimensionality are critical aspects. Here, we investigate superconducting ${\mathrm{W}}_{0.75}{\mathrm{Re}}_{0.25}$ thin films deposited via UHV dc magnetron sputtering. In order to tune the crystalline phase of the films, we further explored the effect of incorporating ${\mathrm{N}}_2$ during the deposition. The superconducting and normal-state properties as a function of deposition conditions were investigated, revealing the role of the crystal phase on the film transport properties.
