A magnetoresistive apparatus and method of operation with improved
switching characteristics is provided. Switching of a magnetic direction
of a magnetic layer of a magnetoresistive bit is promoted by parallel
rotation of local magnetic direction of ends of the bit toward alignment
with a hard-axis of the bit. Thus, an embodiment provides for expanded
hard-axis magnetic volume of the bit ends to support hard-axis
magnetization through bit shape alteration or doping, for example. A
method provides for applying a hard-axis magnetic field to the bit ends
for initiating switching and applying an easy-axis magnetic field for
completing switching.
