HTTP:: Gas Exhibits Magnetic Behavior
--------
After more than 10 years of arduous debate in the international scientific community as to whether gas and liquids can exhibit magnetic properties, and become ferromagnets, an international collaboration has brought the final arguments to the table. The scientists involved in the new research managed to observed magnetic behavior in an atomic gas for the first time, essentially settling this issue. The lithium-atom gas was trapped in the focus of an infrared laser beam at the time of the study.“Magnets are all around us â€" holding postcards on the refrigerator, pointing to magnetic north on a compass, and in speakers and headphones â€" yet some mysteries remain. We have perhaps found the simplest situation in which permanent magnetism can exist,” explains University of Toronto professor of physics Joseph H. Thywissen. He is also a visiting member at the Massachusetts Institute of Technology-based team that was in charge of the new research. The atomic gas was less than!
a millionth of a degree above absolute zero, which is at -273 degrees Celsius (roughly 150 nK).The ferromagnetic behavior became obvious to the investigators when they gradually increased the repulsive forces between the atoms in the mix. Other traits modified as well. At first, the gas increased in volume considerably, and then shrunk...
