Astronomers have detected a new slowly rotating radio pulsar as part of the SUrvey for Pulsars and Extragalactic Radio Bursts (SUPERB). The newly found object, designated PSR J2251−3711, turns out to be one of the slowest ...
To increase the efficiency of microchips, 3-D structures are now being investigated. However, spintronic components, which rely on electron spin rather than charge, are always flat. To investigate how to connect these to ...
