Abstract : Magnetic force microscopy imaging enable to extract the main magnetic parameters (saturation magnetization, anisotropy, domain size, exchange constant). The magnetoresistance and the extraordinary Hall effect of the material have been characterized using nanostructures patterned on the multilayer. Both the magnetization reversal mode and the magnetotransport properties are found to depend strongly on the nanowire width. The relatively low coercive field, the high anisotropy, and the possibility to control domain wall motion in sub-100 nm wires make this system an interesting alternative to Pt-based multilayers for spin-transfer torques experiments. © 2018 Author(s).
