(Phys.org)—TDK has realized increased areal density of its hard disk drives. TDK has set a new record, compared to previous areal density at 1Tbit/inch2, with the new stat of increased density to 1.5Tbits/inch2. The point ...
The spin Hall effect (SHE) enables us to create spin current in non-magnetic materials without using ferromagnetic materials. It is a crucial element in the central idea behind spintronics, that of manipulating currents ...
