Vortex-antivortex pairs found in magnetic trilayers

A international team of researchers has discovered magnetic vortex-antivortex pairs arising from correlated electron spins in a newly engineered trilayer material. The discovery could advance memory cells and points to the ...

Camera captures microscopic holograms at femtosecond speeds

Researchers from ITMO University have built a setup for recording holograms of tiny objects like living cells at femtosecond speeds. The new method reconstructs the phase topography of a sample according to deformations that ...

'Magic' alloy could spur next generation of solar cells

In what could be a major step forward for a new generation of solar cells called "concentrator photovoltaics," University of Michigan researchers have developed a new semiconductor alloy that can capture the near-infrared ...

Researchers discover way to make solar cells more efficient

When it comes to improving the efficiency of solar cells, a group of University of Wyoming professors has discovered a way to do so by adding manganese atoms—an alternate metal—to the mix. Doing so, they found, dramatically ...
