For almost 100 years, scientists believed there were only two main types of magnets. One is the familiar ferromagnet, the kind found on refrigerators and in many electronic devices. The other is the antiferromagnet, a less obvious type whose magnetic properties cancel out and remain hidden at larger scales. In recent years, researchers have identified […]
