New, intelligent materials for use in mechanical actuators
A research team at the Department of Physics at the Public University of Navarre are developing new, "intelligent" materials which have the capacity for changing shape when a magnetic field is applied to them. These materials may be used for the generation of ultrasonic signals, in the manufacture of loudspeakers and sonars or in... view more... (2004-01-29)
Nanophysicists find unexpected magnetic effect
Spanish and U.S. physicists studying nanoelectronics have found that size really does matter when it comes to predicting the behavior of electrical contacts that are just one atom wide. view more (2009-04-30)
Graphite mimics iron's magnetism
Researchers of Eindhoven University of Technology and the Radboud University Nijmegen in The Netherlands show for the first time why ordinary graphite is a permanent magnet at room temperature. view more (2009-10-05)
Finnish SPIN researchers at forefront of development: Spintronics can bring electronics down to size
Researchers working on the room temperature spintronics (SPIN) research project are the first in Europe to successfully produce GaMnN layers, which are ferromagnetic at room temperature. The layer properties were examined using electric, optic, x-ray and positron measurements. The Academy-funded SPIN project is comprised of four participating... view more... (2005-03-17)
Ames Laboratory researchers rethink zinc
Try as they might, ancient alchemists could never turn lead into gold. Neither can the members of the Novel Materials group at the U.S. Department of Energy's Ames Laboratory. But these physicists do have a way with materials, and they can get them to do some pretty amazing things. view more (2007-04-18)
Argonne scientists pinpoint mechanism to increase magnetic response of ferromagnetic semiconductor
When squeezed, electrons increase their ability to move around. In compounds such as semiconductors and electrical insulators, such squeezing can dramatically change the electrical- and magnetic- properties. view more (2009-02-26)
Physicists observe magnetism in gas for the first time
An international team of physicists has for the first time observed magnetic behaviour in an atomic gas, addressing a decades-old debate as to whether it is possible for a gas or liquid to become ferromagnetic and exhibit magnetic properties. view more (2009-10-05)
NRL scientists demonstrate efficient electrical spin injection into silicon
Scientists at the Naval Research Laboratory (NRL) have efficiently injected a current of spin-polarized electrons from a ferromagnetic metal contact into silicon, producing a large electron spin polarization in the silicon. view more (2007-07-17)
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)
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)
Improved Spin Transistor from Oxford University
Researchers at Oxford University’s Physics Department have developed an improved version of the “spin transistor,” a device which has the principle operating characteristics of a conventional transistor but with the added benefit of a current output dependent on the strength of the external magnetic field. This exciting new... view more... (2002-08-15)
Measurements from the edge: magnetic properties of thin films
Materials researchers at the National Institute of Standards and Technology (NIST), together with colleagues from IBM and the Massachusetts Institute of Technology, have pushed the measurement of thin films to the edge-literally-to produce the first data on how the edges of metallic thin films contribute to their magnetic properties. view more (2007-10-01)
Einstein's magnetic effect is measured on microscale
A gyromagnetic effect discovered by Albert Einstein and Dutch physicist Wander Johannes de Haas-the rotation of an object caused by a change in magnetization-has been measured at micrometer-scale dimensions for the first time at the National Institute of Standards and Technology (NIST). view more (2006-10-02)
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)
Changing the rings: a key finding for magnetics design
Researchers at the National Institute of Standards and Technology's Center for Nanoscale Science and Technology (CNST) have done the first theoretical determination of the dominant damping mechanism that settles down excited magnetic states-"ringing" in physics parlance-in some key metals. view more (2007-08-06)
Press invite: 26th International Conference on the Physics of Semiconductors
A laser-based system that could revolutionise both medical imaging and communications, progress towards building the first solid state `quantum` computer and developments in nanotechnology are just some the topics being featured at the 26th International Conference on the Physics of Semiconductors. The five-day conference is being organised by the... view more... (2002-07-10)
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)
NRL generates, modulates, and electrically detects pure spin currents in silicon
Scientists at the Naval Research Laboratory (NRL) have generated, modulated and electrically detected a pure spin current in silicon, the semiconductor used most widely in the electronic device industry. view more (2007-12-04)
Magnet Made Of Pure Carbon
All known magnets contain metals and so far scientists believed that non-metallic material could not behave like a strong magnet. However, at the end of 20th century, some organic substances with strong magnetic properties were found, but they were magnetic only at very low temperatures, just above liquid helium. It seemed impossible to obtain... view more... (2001-10-24)
Magnetic transistor could 'dial in' quantum effects
A team of theoretical and experimental physicists from Rice University is preparing a unique probe in hopes of "dialing in" elusive quantum states called "quantum criticalities." view more (2005-12-13)
