Researchers from the University of Cambridge and TU Eindhoven have created a nanoscale magnetic circuit capable of moving information through three-dimensional space. This so-called 3D nanoprinting, combined with traditional methods enables functional circuits that can process information, which could lead to future spintronics device development.

To create these 3D nanomagnets, the researchers used an electron microscope along with a gas injector to 3-D print a suspended scaffold on a traditional 2-D Silicon substrate. After 3-D nano-printing, magnetic material is deposited over the whole ensemble to allow information transport.
