Electrical engineers are starting to consider materials made from organic molecules -- including those made from carbon atoms -- as an intriguing alternative to the silicon and metals used currently in electronic devices, since they are easier and cheaper to produce. A RIKEN-led research team has now demonstrated the origin of magnetism in organic molecules, a property that is rarely found in this class of material, but is vital if a full range of organic electronic devices is to be created.

(PhysOrg.com) -- The transition-metal monoxide FeO is an archetypal example of a Mott insulatora material that should conduct electricity under conventional band theories but becomes an insulator when measured, especially at low temperaturesand a major iron-bearing component of the Earths interior. Understanding the high-pressure behavior of this material is important for both solid-state physics and Earth science.

The physics buzz reached a frenzy in the past few days over the announcement that the Large Hadron Collider in Geneva is planning to release what is widely expected to be tantalizing--although not conclusive--evidence for the existence of the Higgs boson, the elementary particle hypothesized to be the origin of the mass of all matter.
