Man versus machine: Can AI do science?

15-Jan-2020

Over the last few decades, machine learning has revolutionized many sectors of society, with machines learning to drive cars, identify tumors and play chess - often surpassing their human counterparts. Now, a team of scientists based at the Okinawa Institute of Science and Technology Graduate ...

Unprecedented insight into two-dimensional magnets using diamond quantum sensors

29-Apr-2019

For the first time, physicists at the University of Basel have succeeded in measuring the magnetic properties of atomically thin van der Waals materials on the nanoscale. They used diamond quantum sensors to determine the strength of the magnetization of individual atomic layers of the material ...

Valence-bond revival in magnetism

Researchers bring to light fundamental behavior of intricate magnetic states–quantum spin liquids

18-Apr-2019

Magnets are prone to order. Their basic constituents, individual magnetic moments, tend to align at low temperatures, thus forming “frozen” magnetically ordered states. A minority of magnets break this trend and reveal peculiar characteristics that can be paralleled to a never-freezing (quantum) ...

A special phenomenon in magnets

A compass pointing West

02-Apr-2019

Researchers from the Paul Scherrer Institute PSI in Villigen and the ETH Zurich have discovered a special phenomenon in magnets. This phenomenon takes place at the nanoscale and enables magnets to be assembled in unusual configurations, which could also be useful for computer technology and data ...

First high-temperature single-molecule magnet

23-Oct-2018

A team of scientists led by Professor Richard Layfield at the University of Sussex has published breakthrough research in molecule-based magnetic information storage materials. The group at the University of Sussex, working with collaborators at Sun-Yat Sen University in China and the University ...

New devices based on rust could reduce excess heat in computers

Physicists explore long-distance information transmission in antiferromagnetic iron oxide

14-Sep-2018

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 existing devices. Conventional devices using current technologies have ...

Particles pull last drops of oil from well water

Nanoscale solution to ‘produced water’ problem

17-Aug-2018

Oil and water tend to separate, but they mix well enough to form stable oil-in-water emulsions in produced water from oil reservoirs to become a problem. Rice University scientists have developed a nanoparticle-based solution that reliably removes more than 99 percent of the emulsified oil that ...

Creating a 2-D platinum magnet

10-Apr-2018

University of Groningen physicists have induced magnetism in platinum with an electric field created by a paramagnetic ionic liquid. As only the surface of the platinum is affected, this creates a switchable 2D ferromagnet. Platinum is used a lot in jewellery and electronics. Although this ...

Unexpected effect could lead to lower-power memory, computing devices

20-Mar-2018

An unexpected phenomenon known as zero field switching (ZFS) could lead to smaller, lower-power memory and computing devices than presently possible. The image shows a layering of platinum (Pt), tungsten (W), and a cobalt-iron-boron magnet (CoFeB) sandwiched at the ends by gold (Au) electrodes on ...
