The word “crystal” is a technical term; iron and steel, for example, are crystals whereas glass is not. In fact, "crystal" means materials of a crystalline structure.
Just like any other kind of material, crystals can change their structure. For example, if the temperature rises sufficiently, it passes from a solid to a liquid state. But other, not so noticeable, structural changes also take place, such as those that occur in the solid state, itself. These changes are known as solid-to-solid phase transitions and are induced by changes in either temperature or pressure. Moreover, the electrical and magnetic properties of the crystals are affected during these transitions and are, thereby, of great interest for technology.
At the Leioa (Bizkaia) campus of the University of the Basque Country (EHU), a research team has been analysing solid-to-solid transitions of crystals. They selected a group of crystals known as double perovskites for this purpose. Prior to the analysis a certain amount of preparation work is required in the lab: the perovskites have to be synthesised.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
