Abstract :
Magnetization reversal process in current perpendicular to the plane giant magnetoresistance pillars with magnetostatically coupled ferromagnetic layers was investigated in NiFe/Cu multilayer. The parabolic magnetoresistance curve representing the reversible inversed magnetization rotation due to the fringe field coupling was observed. A numerical model was proposed to explain the magnitude of the fringe field coupling.
