Chemists establish fundamentals of ferroelectric materials

Ferromagnetic materials, like compass needles, are useful because their magnetic polarization makes them rotate to align with magnetic fields. Ferroelectric materials behave in a similar way but with electric, rather than ...

Consistency of Earth's magnetic field history surprises scientists

Earth's magnetic field is generated by the motion of liquid iron in the planet's core. This "geodynamo" occasionally reverses its polarity—the magnetic north and south poles swap places. The switch occurs over a few thousand ...

Diamonds may be the key to future NMR/MRI technologies

Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have demonstrated that diamonds may hold the key to the future for ...

Magnetic monopoles in spin ice crystals

Today one of the major goals of physicists is to unify the forces of nature into a Grand Unified Theory that could portray a more elegant and comprehensive representation of the Universe. One step towards this big theory ...

Titan's atmosphere even more Earth-like than previously thought

Scientists at UCL have observed how a widespread polar wind is driving gas from the atmosphere of Saturn's moon Titan. The team analysed data gathered over seven years by the international Cassini probe, and found that the ...
