QUB’s scientist leads international team to crack 60-year-old mystery of Sun’s magnetic waves

For more than 60 years observations of the Sun have shown that as the magnetic waves leave the interior of the Sun they grow in strength but until now there has been no solid observational evidence as to why this was the case.

More energy instead of heat by planting magnetic spins into a quantum dot

LANL researchers demonstrate that by incorporating magnetic ions into quantum dots they can greatly enhance useful ‘energy-producing’ interactions so as they become faster than wasteful phonon scattering.

Experimental physicists redefine ultrafast, coherent magnetism

For the first time ever, experimental physicists have been able to influence the magnetic moment of materials in sync with their electronic properties. The coupled optical and magnetic excitation within one femtosecond corresponds to an acceleration by a factor of 200 and is the fastest magnetic phenomenon that has ever been observed.
