We investigated the anomalous Hall effect and longitudinal magnetoresistance in ferrimagnetic Co90Gd10 thin films with thicknesses from 5 to 35 nm and temperatures from 80 to 300 K. As the temperature increases from 80 to 300 K, the saturation magnetization of Co90Gd10 increases from 720 to 844 emu/cm3. However, the scaling law \sigma xy – \sigma xx^{n} with $n =2.3$ holds surprisingly well. Our results indicate that the scaling law usually reported in ferromagnetic materials remains valid for ferrimagnetic materials, which undoubtedly suggested the universality of the scaling law.
