Being a promising class of materials exhibiting coupled magnetic and electric ordering properties at ambient temperatures, the magnetic structure of the layered perovskites YBaCuFeO 5 —and thus ...
Why do cold thin sheets of carbon offer no resistance to electric currents? Two experiments are bringing us closer to an answer – and maybe even to practical room-temperature superconductors.
For decades, scientists have tried to understand how Earth’s inner core operates compared with the rest of the planet. Now, a team of researchers has found compelling evidence that it’s changing shape ...
