Researchers at Princeton University have made a breakthrough in understanding kinetic magnetism by using ultracold atoms in a laser-built lattice to image a new type of polaron, revealing how impurity motion in an atomic array causes robust magnetism at high temperatures. Credit: SciTechDaily.com

The research team directly imaged the microscopic object responsible for this magnetism, an unusual type of polaron.

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 nature, and scientists are still discovering the mechanisms that drive them.
