The ability to conduct heat is one of the most fundamental properties of matter, crucial for engineering applications. Scientists know well how conventional materials, such as metals and insulators, ...

A Fargo-based company has come up with a revolutionary way to produce massive quantities of portable heat using magnets instead of flame. The machines, capable of producing millions of British thermal ...

In conventional heat-assisted magnetic recording (HAMR), a laser is used to locally heat the recording medium to facilitate data writing. However, the thermal energy applied is largely dissipated ...

Magnetic solids can be demagnetized quickly with a short laser pulse, and there are already so-called HAMR (Heat Assisted Magnetic Recording) memories on the market that function according to this ...

Scientists at the U.S. Department of Energy's Ames National Laboratory have created a magnetic heat pump that works just as well as standard air conditioners and heaters without using harmful ...
