ABSTRACT:
A magnetic element which can switch states using a relatively lower magnetic field. The magnetic element comprises first and second magnetic layers separated by an intermediate layer. The magnetization of the first magnetic layer is fixed in a first direction parallel to the easy axis. The second magnetic layer comprises first and second magnetization vectors which are in opposite directions to create a magnetic boundary therein. The magnetic boundary can be driven out of the second magnetic layer by shifting the boundary along a first or second direction along the easy axis.
