Tunable Anisotropy of Co-Based Nanocomposites for Magnetic Field Sensing and Inductor Applications

A method of controlling a nano-crystallization process in one or more geometries, the process comprising:

• producing an amorphous precursor to a nanocomposite, the amorphous precursor comprising a material that is substantially without crystals not exceeding 20% volume fraction;
• performing devitrification of the amorphous precursor, wherein the devitrification comprises a process of crystallization;
• forming, based on the devitrification, the nanocomposite with nano-crystals that comprise an induced magnetic anisotropy;
• tuning, based on one or more of composition, temperature, configuration, and magnitude of stress applied during annealing and modification, the magnetic anisotropy of the nanocomposite;
• and
• adjusting, based on the tuned magnetic anisotropy, a magnetic permeability of the nanocomposite.
