Most materials we use in everyday life expand slightly when heated and return to their original size when cooled. In addition ...

Ferroelectric crystals are a special class of materials that exhibit spontaneous electric polarization, which can be reversed by applying an external electric field. These crystals have a ...

Most materials we use in everyday life expand when they are heated. Metals, plastics, and many other materials grow slightly ...

(Nanowerk Spotlight) In their pursuit of device miniaturization, researchers are exploring the untapped potential of two-dimensional materials. These atomically thin crystals, with their unique ...

Scientists have discovered that ordinary ice is a flexoelectric material, capable of generating electricity when bent or unevenly deformed. At very low temperatures, it can even become ferroelectric, ...

Today’s computers store information in magnetic hard drives, keeping files safe even when the device is powered off. But to run programs and process information, computers rely on electricity. Each ...

Controlling magnetic states in materials typically requires continuous power or only works in rare, specialized systems. Researchers developed a general theory showing how electric fields can ...

Over the past two decades, spintronics has emerged as one of the most promising frontiers in nanoelectronics, seeking to exploit the intrinsic angular momentum, or spin, of electrons to carry and ...

In a study published in Nano Letters, researchers demonstrated that light can change the electric polarization within the domains of a relaxor material in just trillionths of a second. Depiction of ...
