Rare earth compounds are a group of chemical compounds that contain rare earth elements, which are a set of 17 chemically similar metallic elements found in the lanthanide series and scandium and yttrium. These compounds exhibit unique magnetic, optical, and electrical properties that make them valuable in various applications, including electronics, renewable energy, and advanced materials. Their significance increases in contexts like ferromagnetism and antiferromagnetism due to their interesting magnetic behaviors and interactions.
