Antiferromagnet is attractive for the high-speed dynamics but it is difficult to observe the current driven oscillation by practical current. We proposed the artificial antiferromagnet consisting of the magnetic domains with antiparallel magnetization alternatively and fabricated it by using the 90 degree magnetic coupling.
