Unexpectedly long-range effects in advanced magnetic devices
A tiny grid pattern has led materials scientists at the National Institute of Standards and Technology (NIST) and the Institute of Solid State Physics in Russia to an unexpected finding-the surprisingly strong and long-range effects of certain electromagnetic nanostructures used in data storage. view more (2009-07-02)
Neutron researchers discover widely sought property in magnetic semiconductor
Researchers working at the National Institute of Standards and Technology (NIST) have demonstrated for the first time the existence of a key magnetic-as opposed to electronic-property of specially built semiconductor devices. view more (2008-11-26)
UAB Scientists break the hard drive miniaturisation limit
Magnetic memory-based information storage systems are getting smaller and smaller, while their capacities are getting larger. However, there is a limit to how small they can get. If the tiny magnets used to store information are smaller than around five nanometres (millionths of a millimetre), vibrations caused by temperature can erase their... view more... (2003-07-10)
Nano-layer of ruthenium stabilizes magnetic sensors
A layer of ruthenium just a few atoms thick can be used to fine-tune the sensitivity and enhance the reliability of magnetic sensors, tests at the National Institute of Standards and Technology (NIST) show. view more (2007-08-06)
Argonne scientists prove unconventional superconductivity in new iron arsenide compounds
Scientists at U.S. Department of Energy's Argonne National Laboratory used inelastic neutron scattering to show that superconductivity in a new family of iron arsenide superconductors cannot be explained by conventional theories. view more (2009-01-13)
More evidence for 'stripes' in high-temperature superconductors
An international collaboration including two physicists from the U.S. Department of Energy's Brookhaven National Laboratory has published additional evidence to support the existence of "stripes" in high-temperature (Tc) superconductors. view more (2006-04-27)
Transition Metal Selenites (Mn, Co, Ni, Fe, Cu, Zn and Cd)
The work involved a multidisciplinary task, undertaking the study of phases of mineralogical and physico-chemical interest. Selenites were synthesised, given that they are a new field and likely to present original physical properties. view more (2005-09-30)
A new magnetic phenomenon may improve RAM memories and the storage capacity of hard drives
The application of 'displaced vortex states'-small magnetic circular movements of just a few thousandths of a millimetre-may accelerate the arrival of a new type of magnetic memory (MRAM) that does not disappear when a computer is switched off. view more (2006-03-03)
Physicists describe a new mechanism for metallic magnetism
Predicting the magnetic behavior of metallic compounds is a surprisingly difficult problem for theoretical physicists. view more (2005-08-26)
