| Strictly speaking, there are no examples of materials in which singlet superconductivity and ferromagnetism co-exist. |
|
| At the end of 2000 superconductivity in metal alloys and compounds appeared to remain trapped by a glass ceiling. |
|
| Stripe order can coexist with superconductivity, but it tends to be associated with a drop in the superconducting transition temperature. |
|
| These chemically complex materials can, in fact, provide more information about superconductivity and magnetism than supposedly simple materials. |
|
| Such fields, however, do not wreck triplet superconductivity because the spins of both electrons may point in the same direction as the field. |
|
| Similarly, superconductivity can be destroyed by applying a magnetic field that exceeds some critical value. |
|
| The modulation indicates a competing type of order that can also coexist with superconductivity. |
|
| Many physicists assumed that a more exotic underlying mechanism was responsible for superconductivity in magnesium diboride. |
|
| And Dr Leggett's prize is for work on superfluidity, not superconductivity. |
|
| High-temperature superconductivity is highly sensitive to sample impurities, a princess and the pea phenomenon. |
|
| If there were no phase transitions, phenomena like superfluidity and superconductivity could not occur. |

|
| Indeed, in many areas of physics, such as cold fusion and high-temperature superconductivity, the scientific disputes have been extremely hostile and personal. |
|
| It aims to develop technologies across a wide range of disciplines including superconductivity, nanotechnology, data storage, photonics and power electronics. |
|
| This course will highlight outstanding properties such as superconductivity, colossal magnetoresistance or giant piezoelectricity. |
|
| This is very clear from President Reagan's latest initiative concerning a USD 100 million research programme on superconductivity. |
|
| However, they have revealed problems with existing theories of ferromagnetism and superconductivity that are likely to keep researchers busy for some time to come. |
|
| Similarly, it is very unlikely for singlet superconductivity to appear in the ferromagnetic state because the exchange interaction forbids the formation of Cooper pairs. |
|
| Examples of this abound in the history of science, from the transistor to superconductivity. |
|
| What are the underlying physical mechanisms that cause high-temperature superconductivity? |

|
| Moreover, hydrogen in liquid form is used in cryogenic research, including superconductivity studies. |
|
| A key test to check for superconductivity in materials is called the Meissner effect. |
|
| Such a strong diamagnetism, due to the expulsion of magnetic flux by a supercurrent, is a significant signal of the onset of superconductivity. |
|
| At an even more basic level, sets of electrons called Cooper pairs form superconductivity. |
|
| Once the material is cooled below the critical temperature, the strength of these fluctuations falls and the superconductivity state takes over. |
|
| Project 4 focuses on the electronic properties of oxide superconductors and related materials, and the microscopic origin of superconductivity and other states of matter which they present. |
|
| The main application of ultralow temperature is in the development of the superconductivity state, in which the resistance to the electricity flux is almost zero. |
|
| The Croatians have apparently done their homework, measuring the so-called Meisner effect, a tell-tale of superconductivity in which a magnetic field is expelled from the material. |
|
| A wave of world-wide research activity has followed the breakthrough in superconductivity for which two European scientists were awarded the 1987 Nobel Prize for Physics. |
|
| Dr. Gygax, a Professor Emeritus in the Department of Physics at Simon Fraser, has received NSERC Discovery, and Research Tools and Instruments Grants for work on low-temperature, solid-state physics and superconductivity. |
|
| He says the challenge is to understand what it is about how the electrons are interacting with one another and ordered that gives rise to superconductivity. |
|
| Recently, an international team including researchers from Paris Observatory, has proposed to interprete inflation models by considering them in the framework of superconductivity, critical phenomena and phase transitions. |
|
| In 1993, the trio stunned the global physics community by demonstrating that high-temperature superconductivity involves a different behaviour of electrons than its low-temperature cousin. |
|
| Recently, in collaboration with scientists at Los Alamos Laboratory and the University of Florida, ITU researchers demonstrated the high temperature superconductivity of plutonium compounds. |
|
| Since then, superconductivity has been reported at room temperature and above, opening up the prospect of a new technological revolution in electronics and electrical applications. |
|
| These are systems that exhibit new electronic properties that defy our understanding and predictive ability. Such properties include high-temperature superconductivity, unconventional magnetism and exotic phases of matter. |
|
| The decay length of the nonthermalized signal is determined by the electron-electron scattering rate, renormalized due to superconductivity. |
|
| Currently, superconductivity can only be achieved at extremely low temperatures. |
|
| This enables the use of a standard low temperature cryocooler to cool the magnet to 4 degrees Kelvin, necessary to achieve superconductivity. |

|
|
| Some of the ceramic materials proved to have critical temperatures higher than 160 K, fanning hopes that room-temperature superconductivity was within reach. |
|
| Two electrons mutually attracted to positively charged ions in a material lattice can couple to form a Cooper pair, which is crucial for superconductivity. |
