Wiktionary
- n. chemistry Any of the 14 rare earth elements from cerium (or from lanthanum) to lutetium in the periodic table; because their outermost orbitals are empty, they have very similar chemistry; below them are the actinides.
GNU Webster's 1913
- n. Any rare earth element of the lanthanide series (atomic numbers 57 through 71).

Examples
“If you remember the Periodic Table of Elements from your high school chemistry class, rare earth refers to a group of 17 elements, also called lanthanide elements, with similar metallic characteristics, but differing from other metals.”
Voice of America: Rare Earth Elements Becoming Hot Commodity
“Depending upon which chemist you ask, rare earth elements consist of either: the so-called lanthanide series (elements having atomic numbers from 57 [corresponding to lanthanum] to 71 [corresponding to lutetium]) or the actinide (elements 89 to 103) and lanthanide series.”
The Huffington Post: A Cloud in Every Silver Lining: The New Obstacle to a Green-Tech Revolution

“Depending upon which chemist you ask, rare earth elements consist of either: the so-called lanthanide series (elements having atomic numbers from 57 [corresponding to lanthanum] to 71 [corresponding to lutetium]”
“In this connection, Dr. Seaborg demonstrated that the heavy elements form a "transition" series of actinide elements in a manner analogous to the rare-earth series of lanthanide elements.”
“REE assay values are reported by convention as the combined oxide equivalents REO of the fifteen elements in the lanthanide series + yttrium.”
“Roy next plans on analyzing alloys with added lanthanide, iron, and silicon.”
“He hopes to soon expand his research and analyze alloys doped with lanthanide, iron, and silicon.”
