The production of highly non-equilibrium spin densities in solid-state materials offers an alternative state variable to the electron charge that may allow computation at much lower energy densities, providing a path forward for the extension of computing power and speed. Further, the quantum state of an electron spin is a leading contender for realizing quantum computation in a solid-state system, either as a memory, a qubit, part of a bus, or all of the above. In either case, an internally consistent system of devices and measurements is critical to establishing the fundamental limitations on spin diffusion and decoherence. Therefore, we are exploring novel materials systems ranging from ferromagnetic insulators to Heusler alloys as components of spin injection, transport, and detection systems. As part of a complimentary effort, we are also developing a laboratory scale production method for isotopically enriched materials, particularly, 28Si. Non-isotopically enriched materials are recognized as having reducing spin coherence times due to dephasing from isotopes that have non-zero nuclear spin.
