Abstract

See full text

Magnetic nanocomposites are disclosed with aligned, rod-shaped, rare-earth-free and Pt-free metal domains in a rigid, non-metallic matrix. In some variations, the invention provides a magnetic nanocomposite comprising metallic nanorods dispersed within a continuous and rigid non-metallic matrix. The nanorods have an average nanorod length-to-width ratio of at least 2. The nanorods are alignable and may be aligned in one axial direction with magnetic or mechanical forces. Some variations provide a method of forming a magnetic nanocomposite, comprising: dispersing metal oxide nanorods into a hardenable non-metallic material; thermally or chemically reducing the metal oxide nanorods to form magnetic metallic nanorods; aligning nanorods in one axial direction within the hardenable non-metallic material; and hardening the non-metallic material to form a continuous and rigid non-metallic matrix containing the metallic nanorods.
