The beauty of our study is that we present a smart way of increasing the critical temperature without having to use massively high pressure, and without using complicated structures or sensitive materials.<\/p>\n
\u201cMagnesium diboride behaves in the opposite way to many other materials, where high pressure increases the ability to superconduct. Instead, here we can stretch the material by a few percent and get a huge increase in the critical temperature.\u201d<\/p>\n
In the nanoscale, the atoms vibrate even in really hard and solid materials. In the scientists\u2019 calculations of magnesium diboride, it emerges that when the material is stretched, and the atoms are pulled away from each other and the frequency of the vibration\u2019s changes.<\/p>\n
This means that in this superconductive material, the critical temperature increases \u2013 in one case from 39K to 77K. And if magnesium diboride is instead subjected to high pressure, its superconductivity decreases.<\/p>\n
The discovery of this phenomenon paves the way for calculations and tests of other similar materials or material combinations that can increase the critical temperature further.<\/p>\n
\u201cOne possibility could be to mix magnesium diboride with another metal diboride, creating a nanolabyrinth of stretched MgB2<\/sub> with a high superconductive temperature,\u201d concluded Bj\u00f6rn Alling, Senior Lecturer at the Division of Theoretical Physics, and director of the National Supercomputer Centre at Link\u00f6ping University.<\/p>\nThe research has been funded by the Knut and Alice Wallenberg Foundation, the Swedish Research Council and the Swedish Foundation for Strategic Research, as well as others. It has been conducted with support from the government\u2019s strategic venture, Advanced Functional Materials (AFM), at Link\u00f6ping University.<\/p>\n
