	I think they may mean "gadolinium" -- a trivalent magnetic
	rare-earth element.

	As to the magnetocrygenic stuff, one of the techniques used to
	lower the temperature of liquid helium is let it stabilize in a
	magnetic field, then remove the magnetic field; in a rather sneaky
	thermodynamic way, the helium is "doing work" and it cools off a
	little bit.  I don't know if this is what pop-tronics had in mind.
