Abstract
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.
