A wealth of new materials could be found if that pesky “equilibrium” could be avoided. Accessing these new materials could be achieved using far-from-equilibrium processing, in this case inert gas condensation (IGC). IGC is an ideal method of forming a wide variety of nanomaterials over large composition space, with excellent control over nanoparticle size. The nanoparticles formed by IGC can be isolated from each other, creating nanoscale systems that resist transformations to equilibrium (bulk) structures, both in the as-formed state and upon heat treatment. The resulting unique structures, including solid solutions in normally immiscible systems, new atomic structures (i.e., phases), and core/shell and core/frame geometries, strongly influence magnetic and other functional behavior. For example, extensive solubility of 4d or 5d transition metals into Fe or Co can enhance magnetocrystalline anisotropy. Further, novel ordered crystal structures can form from parent non-equilibrium solid solutions, providing another route to discover new materials. This presentation will cover nanoparticle formation mechanisms, the formation and magnetic properties of extended solid solubility in Co-W and Co-Mo, complete solid solution formation in Fe-Au, and ordered L12 and L10 structures in the Fe-Au system. Other systems will also be covered, including the design of core/shell and core/frame nanoparticles, further demonstrating how IGC can be used to design novel materials and structures.
