Abstract

A method of inducing nuclear spin hyper-antipolarization in a solid material is disclosed and described. The solid material can be subjected to an ultralow temperature and a magnetic field. The solid material can include donor nuclei and a carrier material while the material also has both a nuclear spin and an electron spin which are coupled sufficiently to allow an Overhauser effect. The solid material can be subjected at the ultralow temperature to a light source for a time sufficient to induce a substantial nuclear spin antipolarization in the solid material and form a nuclear spin hyper-antipolarized material. The ultralow temperature and light source are controlled so as to be sufficient to drive a non-equilibrium nuclear Overhauser effect of hyperfine coupled electron and nuclear spins. The resulting nuclear spin hyper-antipolarized material can be used for a variety of applications such as medical imaging and quantum computing. These materials can be readily formed relatively quickly and are generally stable at room temperatures.
