Background:

Plasmonics and magnetism offer pathways to enhance magnetic storage density and energy efficiency.
Light-assisted magnetic storage utilizes nanoplasmonics for improved light confinement and enhancement.

Purpose of the Study:

To devise a novel method for light-driven magnetic memory writing.
To achieve bit downscaling and reduce writing energy in magnetic storage.
To enable controlled demagnetization in magnetophotonic crystals.

Main Methods:

Fabrication of a magnetophotonic surface crystal with truncated-nanocone-shaped Au-TbCo antennas.
Investigation of localized plasmon and surface lattice resonance modes.
Analysis of ultrafast magnetization dynamics and demagnetization efficiency.

Main Results:

A 3-fold resonant enhancement in demagnetization efficiency was observed.
The degree of demagnetization was tunable by activating surface lattice modes.
Ultrafast demagnetization was localized at the nanoscale with controllable extent.

Conclusions:

The developed platform enables controlled, nanoscale ultrafast demagnetization for multistate magnetic memory.
This technology paves the way for light-controlled nanomagnetic systems operating at femtosecond timescales.
