Miniaturization is the magic word when it comes to nanomagnetic devices intended for use in new types of electronic components. Scientists now have proposed the use of ion beams for their fabrication. An ultra-fine beam consisting of around 10 neon ions suffices to bring several hundred atoms of an iron-aluminum alloy into disarray and thereby generate a nanomagnet embedded directly in the material.

Researchers have come up with a procedure that makes it possible to produce thin film tandem solar cells in which a thin perovskite layer is used. The processing of peroveskite takes place at just 50 degrees Celsius and such a process is potentially applicable for low cost roll-to-roll production in future.
