Abstract
In an embodiment, the present disclosure pertains to a method of making a composite. In some embodiments, the method includes applying an external magnetic field to a mixture composed of a plurality of magnetic materials in a container, in which the external magnetic field produces a homogenous and uniform magnetic flux in the container. In some embodiments, the method further includes solidifying the mixture to result in the growth of solvent crystals in the mixture, and subliming a solvent phase of the mixture in the container to thereby form a composite having uniformly aligned magnetic materials. In an additional embodiment, the present disclosure pertains to a composite having uniformly aligned magnetic materials. In some embodiments, a majority of the magnetic materials in the composite are aligned in the same direction.
