Researchers at the Universitat Autònoma de Barcelona, the Materials Science Institute of Barcelona (ICMAB-CSIC), and various German and North American institutions have developed a simple method for measuring the maximum current that coated superconductors can carry. The material will, most likely, be used to manufacture the superconductor wires of the future. The research has been published in the journal, Applied Physics Letters.
Electric currents pass through superconductor materials without resistance, which is a property with many technological applications, but this is only possible when the materials are cooled below a certain temperature and when the current does not exceed a certain value.
The superconductor materials that will, most likely, be used for wires that transport electric energy are called coated conductors. They are formed by the deposition of a film of high-temperature superconductor material on a metallic band. The main advantage with respect to other types of superconductors is that they allow large quantities of electric current to move through them without the need for excessive cooling, yet they keep their superconductor qualities. This makes possible, among other things, the generating of highly intense magnetic fields with lighter superconductors and the transmission of electric current with minimum losses.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
