Suspended layers make a special superconductor

In superconducting materials, an electric current will flow without any resistance. There are quite a few practical applications of this phenomenon; however, many fundamental questions remain as yet unanswered. Associate ...

Insulating antiferromagnetic materials for future computers

Future computer technology based on insulating antiferromagnets is progressing. Electrically insulating antiferromagnets such as iron oxide and nickel oxide consist of microscopic magnets with opposite orientations. Researchers ...

Scientists build a nanocage with antiaromatic walls

Researchers at Tokyo Institute of Technology, the University of Cambridge, and the University of Copenhagen have built a self-assembled nanocage with a very unusual nanospace: Its walls are made of antiaromatic molecules, ...

Biodegradable anti-cancer treatment micro-robot

Professor Hongsoo Choi's research team in the Department of Robotics Engineering & DGIST-ETH Microrobot Research Center (DEMRC) at DGIST (President Young Kuk) succeeded in developing a biodegradable micro-robot that can perform ...

Spinning towards robust microwave generation on the nano scale

Spin-torque oscillators (STOs) are nanoscale devices that generate microwaves using changes in magnetic field direction, but those produced by any individual device are too weak for practical applications. Physicists have ...

Physicists discover new quantum trick for graphene: magnetism

Sometimes the best discoveries happen when scientists least expect it. While trying to replicate another team's finding, Stanford physicists recently stumbled upon a novel form of magnetism, predicted but never seen before, ...

Theory explains ferromagnetic superconductor behavior

Researchers from France and Russia have offered a theoretical explanation for the behavior of a recently discovered material combining superconducting and ferromagnetic properties. The new theoretical model also predicts ...

A peculiar ground-state phase for 2-D superconductors

The application of large enough magnetic fields results in the disruption of superconducting states in materials, even at drastically low temperature, thereby changing them directly into insulators—or so was traditionally ...
