Scientists studied what happens when very short pulses of laser light strike a magnetic material. Understanding how magnetic correlations change over short timescales is the first step in being able to control magnetism for applications.
Researchers report the climate clues that can be found by analyzing magnetic fossil particles, or magnetofossils.
Scientists have found an energy band gap—an energy range where no electrons are allowed—opens at a point where two allowed energy bands intersect on the surface of an iron-based superconductor. This unusual electronic energy structure could be used for quantum information science and electronics.
There are fossils, found in ancient marine sediments and made up of no more than a few magnetic nanoparticles, that can tell us a whole lot about the climate of the past, especially episodes of abrupt global warming. Now, researchers have found a way to glean the valuable information in those fossils without having to crush the scarce samples into a fine powder.
An international group of researchers has developed a technique that forecasts how tokamaks might respond to unwanted magnetic errors. These forecasts could help engineers design fusion facilities that create a virtually inexhaustible supply of safe and clean fusion energy to generate electricity.
Graphene, an extremely thin two-dimensional layer of the graphite used in pencils, buckles when cooled while attached to a flat surface, resulting in beautiful pucker patterns that could benefit the search for novel quantum materials and superconductors, according to Rutgers-led research in the journal Nature. Quantum materials host strongly interacting electrons with special properties, such as entangled trajectories, that could provide building blocks for super-fast quantum computers. They also can become superconductors that could slash energy consumption by making power transmission and electronic devices more efficient.
A research team led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a technique that could lead to new electronic materials that surpass the limitations imposed by Moore’s Law.
Neutron scattering instruments at ORNL’s HFIR and SNS are undergoing upgrades which will enable them to study magnetic phenomena previously not possible in the US. Incorporating a device for spherical neutron polarimetry enables the ability to characterize complex magnetic systems in new dimensions for materials that could be developed for enhanced data storage and quantum computing technologies.
Physicists have unraveled a mystery behind the strange behavior of electrons in a ferromagnet, a finding that could eventually help develop high temperature superconductivity. A Rutgers co-authored study of the unusual ferromagnetic material appears in the journal Nature.
Materials that can host this exotic liquid-like magnetic state could be harnessed for next-generation energy and computing applications.
