Ecole Polytechnique Fédérale de Lausanne Magnetic devices like hard drives, magnetic random access memories (MRAMs), molecular magnets, and quantum computers depend on the manipulation of magnetic properties. In an atom, magnetism arises from the spin and orbital momentum of its electrons. 'Magnetic anisotropy' describes how an atom's magnetic properties depend on the orientation of the electrons' orbits relative to the structure of a material. It also provides directionality and...

Theoretical Possibility Of Large, Hollow Magnetic Cage Molecules Discovered By VCU Physicists

Virginia Commonwealth University New molecules could be larger than the original Buckminster fullerene with potential applications in technology and health care Virginia Commonwealth University researchers have discovered, in theory, the possibility of creating large, hollow magnetic cage molecules that could one day be used in medicine as a drug delivery system to non-invasively treat tumors, and in other emerging technologies. Approximately 25 years ago, scientists first made the...

How would you like to store all the films ever made on a device the size of an I-phone? Magnets made of just a few metallic atoms could make it possible to build radically smaller storage devices and have also recently been proposed as components for spintronics devices. There's just one obstacle on the way. Nano-sized magnets have only been seen to work at temperatures a few hairs above absolute zero. High temperature nanomagnets deviced by chemistry student Now a chemistry student at the...

In the world of the very small, researchers at Shanxi University in China have announced progress in understanding the single-molecule magnet, which combines the classical macroscale properties of a magnet with the quantum properties of a nanoscale entity. In the Journal of Applied Physics, Hai-Bin Xue and colleagues studied the statistics of how electrons move through a single-molecule magnet to better understand the magnet's inner level structure. Understanding the single-molecule magnet...

With controlled stretching of molecules, Cornell researchers have demonstrated that single-molecule devices can serve as powerful new tools for fundamental science experiments. Their work has resulted in detailed tests of long-existing theories on how electrons interact at the nanoscale. The work, led by professor of physics Dan Ralph, is published in the June 10 online edition of the journal Science. First author is J.J. Parks, a former graduate student in Ralph's lab. The scientists studied...

Finding presents a powerful new tool for nanoscale science experiments Cornell University researchers recently stretched individual molecules and watched electrons flow through them, proving that single-molecule devices can be used as powerful new tools for nanoscale science experiments. The finding, reported in the June 11 issue of the journal Science, probes the effects of strong electron interactions that can be important when shrinking electronics to their ultimate small size...

NEW YORK, August 22, 2005 "“ In a groundbreaking experiment, researchers from The City College of New York (CCNY) and Lehman College have measured the speed of magnetic avalanches and discovered that the process is analogous to the flame front of a flammable substance.  The discovery of a "magnetic flame" could make it easier for engineers to study the dynamics of fire. Magnetic avalanches occur when the polarity of a molecular nanomagnet is changed suddenly and sufficient energy...
