Magnets produced at room temperature using lasers could one day produce better HDDs, faster non-silicon processors — and at 20nm, they are so thin that they could be used almost anywhere, even in the human body

A group of scientists carrying out research in a lab.

• Researchers demonstrate room temperature laser control of magnons in thin magnetic materials
• Visible light pulses tune magnetic frequencies without cryogenic conditions
• Nanometer scale magnets show promise for faster storage and non silicon computing

Researchers have demonstrated a new way to tune magnetic behavior in extremely thin materials using visible laser pulses at room temperature.
