Crystalline films of CoxPt1-x were prepared over the range of x=0.26 to 0.84 atomic fraction by rf sputtering. Magnetization measurements show a wide range of anisotropy conditions including perpendicular anisotropy at intermediate compositions. The magnetic moment per formula unit of Co-Pt increases with dilution which we attribute to a platinum moment of ≊0.3 μB over the entire range of compositions. The Hall effect and anisotropic magnetoresistance are both large at x≊0.4.
