(Phys.org)—A large team of researchers with members from China, the U.K., the U.S. and Japan has developed a material that can switch between multiple phases with distinct electronic, optical and magnetic properties. In ...
In a proof-of-concept study published in Nature Physics, researchers drew magnetic squares in a nonmagnetic material with an electrified pen and then "read" this magnetic doodle with X-rays.

Rare Earth elements, found in the f-block of the periodic table, have particular magnetic and optical properties that make them valuable commodities. This has been particularly true over the last thirty years as more technologies ...
It was another good week for physics as researchers at Ohio State University conducted a landmark study that proved that magnets can control heat and sound—they demonstrated a magnetic field reducing the amount of heat ...
