[21p-CE-1] Artificial magnetic lattices and applications
Keywords:artificial magnetic lattice, magneto-optics, spin wave
The introduction of artificial magnetic structures into magnetic materials can induce novel electromagnetic and spin-wave behavior. Nano- and submicron-meter-scale artificial magnetic lattices (AMLs) can control optical (electromagnetic) waves in magnetophotonic crystals, volumetric magnetic holograms, and labyrinthian magnetic domain structures, and can affect spin waves in magnonic crystals.
In this talk, the fundamental properties of such AMLs, mainly in magnetic garnet films and alloy thin films, are discussed, followed by demonstrations of their applications in optical and spin-wave micro-devices driven by magnetic phase interference: volumetric magneto-optic (MO) hologram memories and three-dimensional MO holographic displays with magnetophotonic crystals; high-speed MO Q-switch micro-chip lasers with iron-garnet films with labyrinthian magnetic domain structures; and highly sensitive magnetic sensors and spin-wave logic circuits with magnonic crystals.
Prospective future spin-wave devices with AMLs will be discussed in the context of the new paradigm of magnonics (electron non-transport electronics), where spin waves play an important role as the information carrier.
