DEFINITION

Classification: 424/9.323

Metal is paramagnetic:

(under subclass 9.322) Subject matter wherein the transition, actinide, or lanthanide metal of the particle is paramagnetic.

(1) Note. A paramagnetic metal is one which is capable of aligning with a magnetic field, but does not itself become magnetized.

(2) Note. For the purposes of this subclass the term "paramagnetic" is intended to include only substances which are stated to be paramagnetic, not those stated to be superparamagnetic or ferromagnetic.
