摘要： A method and magnetic device for improving the desirable properties of a magnetic device, e.g., magnetization uniformity and reproducibility. Moreover the invention provides magnetic cells that are more magnetically homogeneous, with smaller amount of end domain magnetization canting from the average cell magnetization direction. The invention may provide a magnetic memory cell with less variation in switching fields, more spatially coherent dynamical magnetic properties for high speed and processional or coherent magnetic switching, and higher signal due to the increased uniformity. It may provide a magnetic sensor with more spatially coherent magnetic properties for high speed and processional or coherent magnetic switching, and increased signal. It may provide a read head element with more spatially coherent magnetic properties for high speed and processional or coherent magnetic sensing, and increased signal.

摘要： The present invention concerns in a first aspect a spin-valve structure having a first and a second free ferromagnetic layer and a spacer layer positioned between the first and second free ferromagnetic layer, and wherein the first free ferromagnetic layer is positioned on a substrate. In a preferred embodiment of the invention, the first free ferromagnetic layer is in direct contact with the surface of the substrate.
