Researchers make first perovskite-based superlens for the infrared
Superlenses earned their superlative by being able to capture the "evanescent" light waves that blossom close to an illuminated surface and never travel far enough to be "seen" by a conventional lens. Superlenses ...

Researchers take the lead out of piezoelectrics
There is good news for the global effort to reduce the amount of lead in the environment and for the growing array of technologies that rely upon the piezoelectric effect. A lead-free alternative to the current ...

Research suggests more silicon in Earth's lower mantle than thought
For many years geophysicists have argued over the perplexing mystery regarding the amount of silicon in the Earth's mantle that is thought to have arrived there via impacts with asteroids.

Ferroelectric oxides do the twist
(Phys.org) -- Some materials, by their nature, do what we want them to do -- notably, the ubiquitous, semiconducting silicon found in almost every electronic device. But sometimes, naturally occurring materials ...

Optics get magnetic powers
For decades, scientists have studied a class of materials called ‘multiferroics’ in which static electric and magnetic structures are coupled to each other. This allows capabilities such as controlling ...

Researchers demonstrate rare combination of electric and magnetic properties in strontium barium manganite
An electric field can displace the cloud of electrons surrounding each atom of a solid. In an effect known as polarization, the cloud centers move away slightly from the positively charged nuclei, which radically ...

Long-time mystery in cobalt oxides
The existence of an intermediate-spin (IS) state in cobalt oxides has long been a subject of dispute. A recent resonant X-ray scattering experiment has clearly demonstrated Co3+ eg orbital ordering in Sr3YCo4O10.5, ...
