Rare earth compounds are chemical substances that contain one or more of the 15 lanthanide elements, as well as scandium and yttrium, which exhibit unique magnetic, optical, and electronic properties. These compounds are important in various applications, including electronics, catalysts, and advanced materials, and their behavior is often influenced by the interactions between localized f-electrons and the surrounding crystal lattice.
