AI Discovers New Magnets That Could Make Computers Faster
This could mean instant-on computers and phones that never lose data.
Imagine a computer that starts instantly and never loses your work, even if the power goes out. That's the promise of a new type of memory called MRAM, which uses magnets instead of electric charge to store data. But today's MRAM is expensive and tricky to make because it relies on a special kind of magnet that has a magnetic field that can mess with nearby parts.
Now, a team of AI agents (AI that can take actions on its own) has discovered two new materials that could solve this problem. They are called 'Luttinger compensated' magnets, and they act like antiferromagnets (which don't have a stray magnetic field) but can still sort electrons by their spin, which is needed for storing data. The AI designed one candidate from scratch and found another that was first made in 1999 but never recognized for these properties.
This could lead to faster, more power-efficient computer memory that doesn't lose data when you turn off your device. The catch? These materials are still theoretical predictions and need to be tested in real labs. If they work, your next phone or laptop could boot up in a flash and run cooler, saving battery life.
- AI discovered two new magnetic materials that could make computer memory faster and more energy-efficient.
- These materials are a hybrid of two magnet types, avoiding interference and enabling data storage.
- If proven, this could lead to instant-on devices and longer battery life.
