The effect of N-doping on the microstructure and coercivity of the ‘free’ Fe layer in Fe/insulator/Fe trilayers has been examined. Itwas found thatN-doping leads to a magnetic softening of the Fe layer and a corresponding reduction in the grain size. Hard/soft spin-valve trilayers, showing good independent layer reversal, were obtained using N-doped and undoped Fe layers. Ferromagnetic interlayer coupling was found in these trilayers that could be well described by a N´eel coupling mechanism. Nonuniform reversal of the harder Fe layer, once incorporated in the trilayer, was also observed and could be reproduced using a simple model in which local variations in the interlayer coupling energy are considered. Such variations are likely to be caused by structural inhomogeneity in the films. N-doping is potentially important as a method for tailoring the coercivity of the ‘free’ layer in spin-valves comprising high-polarization magnetic materials.
