(Phys.org)—Similar to the way that a conventional magnetic resonance imaging (MRI) machine uses large magnets to generate 3D images, physicists have developed a proposal for a quantum nano-MRI machine that would use the ...
(Phys.org)—A research team including scientists from the National Institute of Standards and Technology (NIST) has confirmed long-standing suspicions among physicists that electrons in a crystalline structure called a kagome ...

(Phys.org) —Normally, the strength of a magnetic field increases as you get closer to a magnet and decreases as you move further away—a concept easily understood when placing magnets near a refrigerator, for instance. ...
Hopfions, magnetic spin structures predicted decades ago, have become a hot and challenging research topic in recent years. In a study published in Nature, the first experimental evidence is presented by a Swedish-German-Chinese ...
