Mellnik and Ralph pioneer use of spin torque in efficient computer memory

Alex Mellnik and Dan Ralph, in partnership with Nitin Samarth at Penn State, have a novel approach to computer memory they call a "topological insulator." Using the spin orientation of electrons their approach could lead to memory devices that are 10 times more efficient than any other known methods.
