UK-research and development of new carbon based superconducting materials can reduce the cost of magnetic resonance scanner

According to the United States physicist organizations network on May 25, reported that the Chair and the Durham University researchers found that through the imposition of certain pressure, changes in the Crystal structure of C60, a different crystal structure of C60 Cs3C60 from magnetic superconductor-insulator transition to, and their superconducting transition temperature from 38K into 35K.

Researchers said the new discovery will help to reduce such as magnetic resonance imaging scanner and other dependent superconductor energy storage applications.

Researchers in the latest issue of the journal nature on the author notes that they use United Kingdom Rutherford Appleton Laboratory · Spallation Neutron Source (ISIS) and synchrotron radiation (Diamond) and is located in France's European Synchrotron Radiation Facility successfully proved that metal Atomic cesium (Cs) and Bucky ball (carbon atoms in a kind of natural molecules, also known as the C60, its molecular structure similar to Buckminster Fuller designed some · Dome, thus the name) of the new substance Cs3C60 itself does not conduct electricity, but it will in squished into a high-temperature superconductors.

Applied to the object of C60 systolic pressure makes the body-centered cubic structure into FCC crystal structure, at the same time, overcome a repulsion between electronic, e-mail to "double pair", without any resistance through the material.

The research was United Kingdom engineering and physical Sciences Research Council funded a study on the part of the project, designed to investigate what methods can be used to produce at higher temperatures of superconductors, reducing costs for these substances at the proper temperature, a wider application.

Researchers said the C60 and alkali effect can form AxC60 (A representative of potassium, rubidium, cesium, etc.), they are superconductors.

Carbon-based superconducting material advantage lies in that different carbon structure with different characteristics, therefore, manufactured substances with different features and properties. Carbon-based superconducting materials structure flexibility allow scientists to better clarify the HTS-generated internal mechanism, learn how to produce more high-temperature superconductors, carbon-based high-TC superconducting materials or will become mainstream in the future.

Professor of inorganic chemistry of the University of Liverpool · Robert Matthew yeniseysk said this is the first time that control a high temperature superconductors in molecules are arranged to control their properties, such as C60 can do this.

United Kingdom Durham University Professor Cosmas · Laplacian Desmond said, a new study on the development of high-temperature superconducting areas is very important because it allows people to see the superconductivity in when breakthrough insulation condition "peepthrough", regardless of the specific structure of the atom, and how this is any matter past.
