Abstract The average spontaneous magnetizationM s at room temperature of electrodeposited amorphous Co−P samples was measured as a function of the average phosphorus contentc P by a magnetometer method. As the relation is linear it is also valid for the dependence of the localM s on the localc P .Ferromagnetic resonance (FMR) yielded the averageM s of surface layers of about 1 μm thickness (skin depth). Thus composition profiles could be obtained by stepwise thinning the samples and measuring FMR after each step. In some cases the gradient of phosphorus concentration reached 40 at. %/mm whereas the corresponding in-plane quantity is smaller by nearly 3 orders of magnitude. The composition distribution was not changed by long time annealing below crystallisation temperature.
