Researchers Extend Electron Spin In Diamond For Incredibly Tiny Magnetic Detectors
2013-05-10 10:18:01

Lawrence Berkeley National Laboratory From brain to heart to stomach, the bodies of humans and animals generate weak magnetic fields that a supersensitive detector could use to pinpoint illnesses, trace drugs — and maybe even read minds. Sensors no bigger than a thumbnail could map gas deposits underground, analyze chemicals, and pinpoint explosives that hide from other probes. Now scientists at the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley...

Scientists find new magic in magnetic material From powerful computers to super-sensitive medical and environmental detectors that are faster, smaller and use less energy – yes, we want them, but how do we get them? In research that is helping to lay the groundwork for the electronics of the future, University of Delaware scientists have confirmed the presence of a magnetic field generated by electrons which scientists had theorized existed, but that had never been proven until...

Professor Weimin Chen and his colleagues at Linköping University, in cooperation with German and American researchers, have succeeded in both initializing and reading nuclear spins, relevant to qubits for quantum computers, at room temperature. The results have just been published in the renowned journal Nature Communications. A quantum computer is controlled by the laws of quantum physics; it promises to perform complicated calculations, or search large amounts of data, at a...

An international team of scientists has shed new light on a fundamental area of physics which could have important implications for future electronic devices and the transfer of information at the quantum level. The electrical currents currently used to power electronic devices are generated by a flow of charges. However, emerging quantum technologies such as spin-electronics, make use of both charge and another intrinsic property of electrons — their spin — to transfer and...

All-optical switching promises terahertz-speed hard drive and RAM memory Researchers at the U.S. Department of Energy´s Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used in magnetic memory technologies. Magnetic switching is used to encode information in hard drives, magnetic random access memory and other computing devices. The discovery, reported in the April 4...

Helmholtz Association of German Research Centres In their latest experiment, Prof. Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter at the Hamburg-based Center for Free-Electron Laser Science (CFEL) and Dr. Michael Gensch from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) investigated together with other colleagues from the HZDR, the United Kingdom, and Japan if and how superconductivity can be systematically controlled. The objective of their...

To engineers, it´s a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists at the University of Illinois and the University of Pennsylvania found that for copper-containing superconductors, known as cuprates, electrons are not enough to carry the current. “The story of electrical conduction in metals is told entirely in terms of electrons.  The cuprates show that there is something completely new to be understood beyond...

Weizmann Institute researchers suggest one can affect an atom´s spin by adjusting the way it is measured One of the most basic laws of quantum mechanics is that a system can be in more than one state — it can exist in multiple realities — at once. This phenomenon, known as the superposition principle, exists only so long as the system is not observed or measured in any way. As soon as such a system is measured, its superposition collapses into a single state. Thus, we, who...
