In a magneto-electric material, a magnetic field can induce a ferroelectric moment-a displacement of the ions that creates an electric field. Similarly, an electric field can induce a change in the material's magneti...
Two materials, the cuprates, discovered in the mid-1980s, and the iron-based pnictides, discovered in 2008, have been classified as unconventional superconductors. In these materials, the mechanism for superconductivity is believed to be different to that of conventional superconductors, such as aluminum, in which lattice vibrations bind electrons into the so-called Cooper pairs that carry the supercurrent.
The fast pace of growing computing power could be sustained for many years to come thanks to new research from the UK's National Physical Laboratory (NPL) that is applying advanced techniques to magnetic semiconducto...
The tunnel effect of magnetization, a highly unusual property of the world of quantum mechanics discovered by the Magnetism Group of the Department of Fundamental Physics at the University of Barcelona (UB), led by Profe...
Physicists have taken a significant step toward creation of quantum networks by establishing a new record for the length of time that quantum information can be stored in and retrieved from an ensemble of very cold atoms. Though the information remains usable for just milliseconds, even that short lifetime should be enough to allow transmission of data from one quantum repeater to another on an optical network.
Materials known as 'multiferroics' hold great promise as memory storage devices owing to coupling between their magnetic and electric properties. Alas, in the multiferroic materials known to date, this coupling typically is very weak and limited to low temperatures, hampering their uptake in commercial applications.
Under the theme of nano- and molecular materials and devices, the 337th session of the Xiangshan Science Conferences convened from 2 to 4 December in Beijing. This symposium was chaired by Prof. ZHU Daoben from the CAS Institute of Chemistry, Prof. TONG Zhenhe from the CAS Technical Institute of Physics and Chemistry, Prof. GAO Song from School of Chemistry and Molecular Engineering, Peking University and Prof. ZHANG Xi from Department of Chemistry, Tsinghua University.
The investigation of complex materials such as high-temperature superconductors is problematic because of the presence of disorder and many competing interactions in real crystalline materials.
A team led by Stanford researchers has developed a prototype blood scanner that can find cancer markers in the bloodstream in early stages of the disease, potentially allowing for earlier treatment and dramatically improved chances of survival.
Scientists studying a material that appeared to lose its ability to carry current with no resistance say new measurements reveal that the material is indeed a superconductor - but only in two dimensions. Equally surprising, this new form of 2-D superconductivity emerges at a higher temperature than ordinary 3-D superconductivity in other compositions of the same material.
