Single molecule magnet used as a scanning magnetometer

A team of researchers from the University of California and Fudan University has developed a way to use a single molecule magnet as a scanning magnetometer. In their paper published in the journal Science, the group outlines ...

Magnetisation controlled at picosecond intervals

A terahertz laser developed at the Paul Scherrer Institute makes it possible to control a material's magnetisation at a timescale of picoseconds. In their experiment, the researchers shone extremely short light pulses from ...

Controlling skyrmions for better electronics

Physicists at the University of Hamburg managed for the first time to individually write and delete single skyrmions, a knot-like magnetic entity. Such vortex-shaped magnetic structures exhibit unique properties which make ...

Physicists store short movies in an atomic vapor

The storage of light-encoded messages on film and compact disks and as holograms is ubiquitous---grocery scanners, Netflix disks, credit-card images are just a few examples. And now light signals can be stored as patterns ...

Nanospheres stretch limits of hard disk storage

(PhysOrg.com) -- A new magnetic recording medium made up of tiny nanospheres has been devised by European researchers. The technology may lead to hard disks able to store more than a thousand billion bits of information in ...
