Author
Written by Tom Garlinghouse for the Department of Physics

Not all magnets are the same. When we think of magnetism, we often think of magnets that stick to a refrigerator’s door. For these types of magnets, the electronic interactions that give rise to magnetism have been understood for around a century, since the early days of quantum mechanics. But there are many different forms of magnetism in…
