Properties
In addition to the properties included in the table at right, the magnetic properties of bulk amounts of LaC82 (isolated from various hollow fullerenes) have been tested. Magnetization data for an isolated LaC82 isomer were obtained using a SQUID magnetometer at temperatures ranging from 3 to 300 K. For LaC82 the inverse susceptibility as a function of temperature was observed to follow a Curie-Weiss law. The effective magnetic moment per LaC82 was found to be 0.38μB.
Lanthanum carbide has also shown superconductive properties when converted into a layered lanthanum carbide halide La2C2X2 (X=Br,I). Investigations using high-resolution neutron powder diffraction measurements from room temperature to 1.5 Kelvin showed that it has superconductive properties at about 7.03 Kelvin for X=Br and at about 1.7 Kelvin for X=I, respectively.

Famous quotes containing the word properties:
“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (1803–1882)
“The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.”
—John Locke (1632–1704)
