New metamaterial offers reprogrammable properties

Over the past 20 years, scientists have been developing metamaterials, or materials that don't occur naturally and whose mechanical properties result from their designed structure rather than their chemical composition. They ...

Lead-free magnetic perovskites

Scientists at Linköping University, Sweden, working with the perovskite family of materials, have developed an optoelectronic magnetic double perovskite. The discovery opens the possibility to couple spintronics with optoelectronics ...
