Single-molecule magnet

A single-molecule magnet is like a very tiny toy that can spin around and around without stopping, even if you pick it up and move it around. It's made of a special kind of material that has tiny molecules that are shaped like little magnets. Just like how a regular big magnet sticks to the fridge, these tiny magnets stick to each other and can spin around.

But here's the cool part: because these magnets are so small, they can spin in all kinds of weird ways that normal magnets can't. And because they're all packed together so tightly, they can spin without bumping into other molecules around them.

Scientists study these single-molecule magnets to learn more about how magnets work and to try to make even tinier and more powerful magnets. They're still figuring out all the ways they could be used, but some ideas include tiny computer memory chips or super-sensitive sensors.
