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...

A new study discusses the electric and magnetic characteristics of a material which could be used in spintronics Materials belonging to the family of dilute magnetic oxides (DMOs) – an oxide-based variant of the dilute magnetic semiconductors – are good candidates for spintronics applications. This is the object of study for Davide Sangalli of the Microelectronics and Microsystems Institute (IMM) at the National Research Council (CNR), in Agrate Brianza, Italy, and colleagues....

Rotating magnetic moments: Applied Physics Letters reports Bochum's physicists led by Prof. Dr. Hartmut Zabel have demonstrated the spin pumping effect in magnetic layers for the first time experimentally. The behavior of the spin pumping had previously only been predicted theoretically. The research team at the RUB has now succeeded in measuring the effect using ultrafast X-ray scattering with picosecond resolution. Through their rotation of the magnetic moments, the so-called magnetic...

Hailed as the new "wonder material," graphene is being tapped by an international research team to help overcome issues associated with increasing the storage density and speed of electronic memory devices. Electronic memory devices, which store information, are increasingly expected to provide not only greater storage density, but also faster access to information. As storage density increases, however, power consumption and unwanted heat generation also increase, and the fidelity of...

Most important milestone in the direct measurement of the magnetic moment of the proton and its anti-particle has been achieved / Focusing the matter-antimatter symmetry Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM), together with their colleagues from the Max Planck Institute for Nuclear Physics in Heidelberg and the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, have observed spin quantum-jumps with a single trapped proton for...

Nuclear magnetic moment provides a highly sensitive probe into the single-particle structure and serves as a stringent test of nuclear models. In recent decades, the facilities with radioactive ion beam models to study nuclear magnetic moments make it possible to measure the magnetic moments of neutron-rich and proton-rich nuclei with high precision. On the theoretical side, many nuclear structure models, including advanced shell models, and self-consistent mean-field theories, have succeeded...

Atoms are proxies for electrons in ultracold optical emulator A Rice University-led team of physicists is reporting the first success in a three-year effort to build a precision simulator for superconductors using a grid of intersecting laser beams and ultracold atomic gas. The research appears this week in the journal Nature. Using lithium atoms cooled to within a few billionths of a degree of absolute zero and loaded into optical tubes, the researchers created a precise analog of a...

Nuclear magnetic moment is one of the most important physical observables. The precise measurement of nuclear magnetic moment and its understanding in microscopic way are quite a challenge in nuclear physics. The research team at Peking University, who has dedicated to the study of nuclear structure and astrophysics for the last decades, has applied the configuration-fixed deformation constrained RMF approach with time-odd component to investigate the ground-state properties of 33Mg and...

Researchers from the Helmholtz-Zentrum Berlin fr Materialien und Energie have, in cooperation with colleagues from Dresden, St. Andrews, La Plata and Oxford, for the first time observed magnetic monopoles and how they emerge in a real material. They publish this result in the journal Science within the Science Express web site on Sept. 3. Magnetic monopoles are hypothetical particles proposed by physicists that carry a single magnetic pole, either a magnetic North pole or South pole. In the...

With a single electron pump, PTB researchers provide "counted" electrons with the desired spin Many hopes are pinned on spintronics. In the future it could replace electronics, which in the race to produce increasingly rapid computer components, must at sometime reach its limits. Different from electronics, where whole electrons are moved (the digital "one" means "an electron is present on the component", zero means "no electron present"), here it is a matter of manipulating a certain...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
