Basically, the spin of electrons rather than their charge is used to map out the 1s and 0s of our data.Diamond Light SourceThat’s the science, but here are the main benefits. First of all, there’s no density change in the current compared with the data storage devices we use today, so upgrading should become easier. Secondly, the antiferromagnetic materials don’t emit an external magnetic field, so there’s less chance of devices interfering with other equipment or being spied on.A lack of magnetic field also means individual regions can be packed very close together, giving us more data in less space. Information can also remain intact without power, and can be written and read at room temperature – all boxes that need ticking when you’re investigating the potential of a next-generation storage technology.The spintronics approach has the potential to increase read and write times by a factor of up to 1,000
