Gadolinite was named after Johan Gadolin who first isolated yttrium from the mineral.

Gadolinium alloys demonstrate the magnetocaloric effect, whereby they operate in magnetic refrigerators. In a magnetic field, the metal heats up and loses the heat to the environment; when it leaves the field, it cools as its domains grab energy to reorient themselves.
