Breaking Through Physical Limits
We are creating novel artificial magnetic materials by leveraging unique quadrupole magnetic coupling, aiming to advance physical properties beyond the limits previously considered insurmountable.
We created an artificial antiferromagnetic state in which the spins of adjacent magnetic domains are antiparallel.
Calculations predict that the magnetization oscillation frequency driven by spin-transfer torque can reach the sub-THz range in orthogonal structures or in materials with low saturation magnetization.
