The magnetization density, M, of a CuNi thin film containing a 30- composition modulation has been deduced from ferromagnetic resonance data between 120 and 325°K. The data imply the existence of high-M regions in the modulated film. At 300°K, M is about 200 emu/cm3, and increases as the temperature decreases. By 125°K, M is significantly larger than that of pure Ni. After most of the modulation was annealed out, M had decreased by an order of magnitude.
