Lanthanide series: A block of 15 metallic elements from lanthanum (57) to lutetium (71) on the periodic table, characterized by the filling of the 4f electron subshell.
Rare-earth metals: A group of 17 elements with similar chemical properties, including the 15 lanthanides plus scandium and yttrium, vital for modern technologies.
Oxidation state: The hypothetical charge an atom would have if all bonds to atoms of different elements were fully ionic.
Coercivity: A measure of a magnetic material's resistance to changes in its magnetization.
