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.

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, ...

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 ...

New ion beam fabrication uses low cost materials to form vertical nanomagnets whose nanostrip geometry boosts sensitivity to magnetic fields and current pulses. (Nanowerk News) Researchers at HZDR ...

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 ...

Magnetic force microscopy (MFM) is one of the modes of scanning probe microscopy (SPM). As the name implies, it is used to map magnetic characteristics. MFM investigates the local magnetic fields at ...

It is anticipated that within just a few decades, the surging volume of digital data will constitute one of the world's largest energy consumers. Now, researchers at Chalmers University of Technology, ...

Magnetic actuators and sensors are used to produce and control motion. Applications include systems such as automotive anti-lock brakes, computer disk drives, and factory automation. In many of these ...

One of the common modes of scanning probe microscopy (SPM) is Magnetic force microscopy (MFM). As indicated by the name, SPM is used to map magnetic properties. On the nanoscale, MFM probes local ...
