The so-called Casimir force or Casimir effect is a quantum mechanical phenomenon resulting from fluctuations in the electromagnetic field between two conducting or dielectric surfaces that are a short ...

Research teams led by Prof. Zeng Changgan and Zhang Hui from the Hefei National Laboratory for Physical Sciences at the Microscale, the University of Science and Technology of China (USTC) of the ...

Since its inception in 1970 1, optical trapping has developed into a large field of investigation and application, catalyzing substantial advances in diverse disciplines such as biophysics 2,3,4, ...

"...a personal field ... as portrayed in many science fiction movies and comic books, that is invisible to the naked eye—that will take some doing." Reading time 5 ...

Scientists have observed atomic magnetic fields, the origin of magnetic forces, for the first time using an innovative Magnetic-field-free Atomic-Resolution STEM they developed. The joint development ...

In this work, we explored theoretically the spatial resolution of magnetic solitons and the variations of their sizes when subjected to a magnetic force microscopy (MFM) measurement. Next to ...

Researchers at Chalmers University of Technology in Sweden published their findings in Advanced Materials, demonstrating a material that allows two competing magnetic forces to coexist within a single ...

How do magnets create a force? Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for ...

What is Magnetic Force Microscopy (MFM)? Magnetic Force Microscopy (MFM) is a scanning probe microscopy technique that allows the imaging and characterization of magnetic properties of materials at ...

Magnetic illusion: a long wire surrounded by a magnetic replicator generates a replica of the wire outside it. (Courtesy: Phys. Rev. Lett. 10.1103/PhysRevLett.125.177204) Physicists in the UK and ...

In MFM, a magnetic-coated AFM probe interacts with magnetic field gradients from the sample, causing detectable forces on the probe's cantilever. To focus on magnetic interactions, MFM is often ...

Researchers at the Hebrew University of Jerusalem have overturned a 180-year-old scientific assumption, proving that the magnetic component of light plays a critical role in how light interacts with ...
