Traditional magnetic separators, however, present a challenge: they generate a magnetic force that is very high near the side of the vessel closest to the magnet and decreases rapidly with distance.

A standard single frequency AFM is comprised of a boron-doped silicon (Si) or silicon nitride (Si 3 N 4) cantilever with a length of a few micrometers and a single crystal diamond tip at the bottom of ...

The joint development team of Professor Shibata (the University of Tokyo), JEOL Ltd. and Monash University succeeded in directly observing an atomic magnetic field, the origin of magnets (magnetic ...

Magnetic separation has become increasingly popular in biomedical science and industry. This technology uses magnetic properties of micro/nano-sized particles to separate macromolecules of interest, ...

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 ...

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 ...
