🧲⚡ What happens when magnets move faster than we thought possible?
In our everyday devices, magnets store information by flipping their polarity—north becomes south, south becomes north. But compared to modern silicon electronics, this process is surprisingly slow.
Enter ultrafast magnetism. When magnets are struck with incredibly short laser pulses—lasting just a millionth of a billionth of a second—they can switch polarity at speeds that outpace silicon-based technology. This startling discovery launched a new field of research and raised fundamental questions about how magnets behave far from equilibrium.
Join Akshay Pattabi, Assistant Professor of Engineering at the University of San Francisco, for a deep dive into the strange and still-unfolding physics behind ultrafast magnetism.
Thirty years after its discovery, the phenomenon remains an active scientific puzzle—one that could reshape how we think about data storage, energy efficiency, and the future of computing. 🔬✨
