An international team of researchers at University of Montpellier, University of Aveiro and University of Coimbra has demonstrated magnetoelectric coupling in a paramagnetic ferroelectric crystal. In their paper published ...
At 23.03 (local time) on Sunday 9 February, Europe's newest mission to study the sun is set to lift off from Cape Canaveral in Florida, US. Called Solar Orbiter, this European Space Agency (ESA) mission will travel to within ...
