Abstract

Magnetoresistance for a tri-layered Ni₈₁ Fe₁₉ / Cu / Ni₈₁ Fe₁₉ nanoring with wires attached to the ring edges has been investigated. The magnetic domain in the tri-layered ring is well defined due to the GMR effect caused by tri-layered structure. Magnetization reversal is controllable in case that a magnetic field is applied along the wire axis, indicating the present system is promising for an electron interferometer.
