A superconductor is a perfect diamagnet, but there is more than this involved in the Meissner effect. |
|
Such a phenomenon, called the Meissner effect, shows that a superconductor is not a perfect conductor with infinite conductivity. |
|
In the past, the Meissner effect has been used to levitate a dipole magnet placed on the surface of a superconductor. |
|
The gyroscope spheres are coated with an ultra-thin layer of metal that becomes a superconductor. |
|
The influence of magnetic substrate on the flux distribution in superconductor films may be modeled. |
|
The group has realized large gains in cryogenics, gyroscope construction, and superconductor research. |
|
Recently, the Grenoble group discovered that uranium rhodium germanium is a ferromagnetic superconductor at ambient pressure. |
|
To the scientists' surprise, tests showed that the resulting compound is a superconductor at cryogenic temperatures below 18.5 kelvins. |
|
A spinning superconductor acts like a very weak magnet, with the poles of the magnet precisely aligned with the axis of the spin. |
|
These magnetic fields are produced, as in the case of the CMS, by a massive coil wound from a continuous superconductor cable 50 km in length. |
|
The superconductor test facility SULTAN, which is operated by a CRPP work group at PSI, is an international first. |
|
But the same group reported a possible room-temperature superconductor of similar composition a couple of years ago. |
|
But it is not a superconductor at any temperature, unless huge pressures are applied to it. |
|
The superconductor business of SMI in Fornaci di Barga, Italy, employs some 100 persons and generated in 2002 net sales of EUR 16 million. |
|
This type of work requires superconductor magnets that only function at very low temperatures. |
|
After all, a superconductor that is both easy to process and can be cooled using electrical refrigerators, rather than messy cryogens, would find many applications. |
|
Consequently, an unpublished manuscript describing a room-temperature superconductor has been spreading with remarkable speed through the scientific community. |
|
If your stove coil were a superconductor, you'd turn it on but it would never heat up because the electrons would whiz through it without resistance. |
|
First off, he runs over journalist Mia, who has been investigating Energreen and its oddly highly valued factory in Poland, where apparently they have been doing their best to develop this superconductor thingamabob. |
|
A spinning superconductor creates a magnetic field whose direction indicates its axis of rotation and therefore, in this case, that of the gyroscope of which the niobium is a part. |
|
|
Researchers studying the crystalline structure of radioactive plutonium have happened onto the first plutonium-based superconductor. |
|
No other superconductor has ever shown evidence of more than one type of electron pairing. |
|
In a superconductor, electrons do not travel solo. |
|
These materials can exhibit a variety of electronic behaviour from semiconductor to superconductor by trapping different proportions of metal guest. |
|
The ultrasound beams generated by the system can be moved to and fro electronically and precisely focused on the interface between the superconductor material and the aluminum. |
|
Niobium is also used for its property as a superconductor in the magnet industry, for optical applications in cameras and eyeglasses, for surgical implants, and for various other uses. |
|
This behavior is the basis for the Meissner effect, which allows a superconductor to levitate above a magnet. |
|
Researchers can tell when the critical current is reached by measuring the resistive voltage on pairs of voltage taps soldered to the superconductor wires. |
|
A superconductor is not affected by external magnetic fields when in its superconducting state due to the Meissner effect, which is a unique property exhibited by them. |
|
The thickness of the superconductor is smaller than the spin diffusion length and the magnetization of the ferromagnetic leads are aligned either parallel or antiparallel. |
|
Conductus recently announced its agreement to merge with Superconductor Technologies, Inc. |
