First observation of a square lattice of merons and antimerons

Scientists have, for the first time, observed a square lattice of merons and antimerons—tiny magnetic vortices and antivortices that form in a thin plate of the helical magnet Co8Zn9Mn3. By finely varying a magnetic field ...

Reflecting antiferromagnetic arrangements

A team led by Rutgers University and including scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has demonstrated an X-ray imaging technique that could enable the development of smaller, ...

The smallest steerable catheter

Scientists have developed a very small magnetic steerable catheter for minimally invasive surgery. Thanks to its variable stiffness, surgeons can perform more complex movements inside the body with a lower risk of injury ...

Superconductivity and ferromagnetism fight an even match

Russian physicists from MIPT teamed up with foreign colleagues for a groundbreaking experimental study of a material that possesses both superconducting and ferromagnetic properties. In their paper published in Science Advances, ...

Keep cool: Researchers develop magnetic cooling cycle

As a result of climate change, population growth, and rising expectations regarding quality of life, energy requirements for cooling processes are growing much faster worldwide than for heating. Another problem that besets ...

New devices based on rust could reduce excess heat in computers

Scientists have succeeded in observing the first long-distance transfer of information in a magnetic group of materials known as antiferromagnets. These materials make it possible to achieve computing speeds much faster than ...

Tuning terahertz beams with nanoparticles

For years, scientists have dismissed terahertz radiation. Why? There were few ways to control this line-of-sight, nonionizing radiation. However, they saw its potential. For example, it could be used for short-range, high-bandwidth ...

Fast, reliable test for microorganism contamination

Food and water-borne illnesses are a common concern around the world. Every year hundreds of millions of water, beverage and food samples need to be tested to detect harmful bacteria.

A new micro-robot delivers drugs in capsules

An international team of researchers, led by Professor Hongsoo Choi, Director of DGIST-ETH Microrobot Research Center, has developed capsule-type microrobots that can encapsulate cells and drugs and deliver them to targeted ...
