Vibrations Raise the Critical Temperature for Superconductivity

Scientists reveal that coupling between electrons and atomic vibrations play a key role in this vexing phenomenon. Read More »

In an iron-based superconductor, model patterns of electron spins show two competing liquid-like magnetic phases. (Positive spins correspond with yellow and red, while negative spins are green and black.)12.14.15Science Highlight

Magnetic Dance at the Threshold of Superconductivity

Near the onset of superconductivity, continuous exchange of electrons occurs between distinct, liquid-like magnetic phases in an iron-based superconductor. Read More »

A scanning probe microscope (SPM) can detect two similar signals, which could lead to ambiguous identification of ferroelectric materials.12.14.15Science Highlight

One Photon or Two?

First mixed matter/anti-matter probe aims to solve decade-old proton puzzle. Read More »

A stripe-shaped magnetic region (domain), shown in blue (top left) in an ultrathin film device (orange structure). The narrowing region of the device causes the current distribution to change (two of the three red arrows change direction), leading to the breakdown of the magnetic domain into circular disk-shaped bubbles, called skyrmions (bottom left) Magnetic skyrmion bubbles (bottom right) were experimentally observed using magnetic imaging.11.01.15Science Highlight

Creating Novel Magnetic Islands for Spintronics

Generating and moving small, stable magnetic islands at room temperature could be the ticket to more energy-efficient electronics. Read More »

Schematic drawing shows an electron (gold sphere) moving in the direction of the green arrow on the surface of a topological crystalline insulator. In this material, the electron’s quantum-mechanical spin (up) (blue arrow) is coupled with the direction of its motion in such a way that reversing its direction of motion would reverse the direction of the spin (down).11.01.15Science Highlight

You Can Have Your Conductor and Insulator, Too

Scientists synthesized a theoretically-predicted material with unusual current-carrying properties that could open the door for next-generation electronics. Read More »
