Abstract
Described is an apparatus which comprises: an input ferromagnet to receive a first charge current and to produce a corresponding spin current; and a stack of metal layers configured to convert the corresponding spin current to a second charge current, wherein the stack of metal layers is coupled to the input magnet.
Claims19
An apparatus comprising:
- a magnet to receive a first charge current and to produce a corresponding spin current;
- and
- a stack of structures, wherein the stack is to convert the corresponding spin current to a second charge current, wherein one structure of the stack of structures is adjacent to the magnet, and wherein the stack comprises a spin metallic super-lattice which includes a lattice of an alloy and a non-alloy metal.
A system comprising:
- a memory;
- a processor coupled to the memory, the processor having an apparatus which includes:
- an input ferromagnet to receive a first charge current and to produce a corresponding spin current;
- and
- a stack of metal layers configured to convert the corresponding spin current to a second charge current, wherein the stack of metal layers is coupled to the input ferromagnet, wherein the stack of metal layers forms a spin metallic super-lattice with a surface alloy, and wherein the spin metallic super-lattice includes a lattice of the surface alloy and a non-alloy metal;
- and
- a wireless interface to allow the processor to communicate with another device.
