A team of Canadian-Bulgarian researchers has developed a promising novel approach for magnetic cooling that's far more efficient and "greener" than today's standard fluid-compression form of refrigeration.

Scientists Explore Ways To Synchronize Magnetic Spins For More Powerful Nanoscale Electronic Devices
2014-04-30 03:07:24

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory are seeking ways to synchronize the magnetic spins in nanoscale devices to build tiny yet more powerful signal-generating or receiving antennas and other electronics.

Ion Beams Used To Create New Kinds Of Valves For Use In Spintronics
2014-02-19 10:26:38

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have tested a new approach to fabricating spin valves. Using ion beams, the researchers have succeeded in structuring an iron aluminium alloy in such a way as to subdivide the material into individually magnetizable regions at the nanometer scale.

An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...
