So far, it has only been possible to image magnetic domains in 2 dimensions. Now, for the first time, Scientists at Helmholtz-Zentrum Berlin have managed to create 3-dimensional images of these domains deep within magnetic materials Every magnetic material is divided into such magnetic domains. Scientists call them "Weiss domains" after physicist Pierre-Ernest Weiss, who predicted their existence theoretically more than a hundred years ago. In 1907, he recognized that the magnetic moments of...

PTB physicists want to improve tumour therapy by heat treatment in cooperation with biomedical physicians from Jena Those who have to fight a powerful enemy must look for allies. This is why physicists from different scientific fields have decided to cooperate with biomedical physicians in order to place the fight against cancer through heat treatment by means of magnetic nanoparticles on a solid, scientific basis. It is the objective of the cooperation to improve the success of the therapy....

While attempting to solve one mystery about iron oxide-based nanoparticles, a research team working at the National Institute of Standards and Technology (NIST) stumbled upon another one. But once its implications are understood, their discovery* may give nanotechnologists a new and useful tool. The nanoparticles in question are spheres of magnetite so tiny that a few thousand of them lined up would stretch a hair's width, and they have potential uses both as the basis of better data storage...

An international research project involving the University of Adelaide has revealed that the magnetic field in the center of the Milky Way is at least 10 times stronger than the rest of the Galaxy. The evidence is significant because it gives astronomers a lower limit on the magnetic field, an important factor in calculating a whole range of astronomical data. Researchers from the Max-Planck-Institute for Nuclear Physics, the University of Adelaide, Monash University and the United States...

Flight-model units for the LISA Pathfinder spacecraft are undergoing a series of tests to determine their magnetic characteristics. The purpose of the tests is to ensure that the stringent magnetic cleanliness requirements of the LISA Pathfinder mission will be met. The LISA Pathfinder mission objective is to verify that a test mass onboard the spacecraft can be kept 'free-floating', subject to unwanted accelerations of less than 3Ö10-14 m/s²....

Sandia researchers have developed a process that can mix tiny volumes of liquid, even in complicated spaces. Researchers currently use all types of processes to try and create mixing, with only "mixed" success. "In small devices," says Sandia materials scientist Jim Martin "people have tried all kinds of pillars and mixing cells to initiate mixing, but these approaches don't work well." Researchers need simpler and more reliable ways to mix in tiny places such as micrometer-sized channels,...

Researchers have unearthed a magnetic force similar to electricity: magnetic charges that act and interrelate like electrical charges. This is the first known use of the magnetic monopoles that subsist in spin ice crystals. A research team wrote that monopoles have the ability to group together and form a "magnetic current" similar to electricity. Called "magnetricity", this new discovery may be utilized in magnetic storage or computers. Magnetic monopoles were first thought to be present 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...


Word of the Day
barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
