The Department of Defense, through the Naval Surface Warfare Center (NSWC), Corona Division, is issuing a pre-solicitation for the procurement of materials and services related to the production of chip-scale mechanical ultra-low frequency antennas. The NSWC seeks specific materials, including TRSX2B PMN-PT and FeGa, with a focus on their characterization via Scanning Quantum Interference Device (SQUID) magnetometry, and requires the delivery of materials within 8 weeks, including a minimum of 10 units of FeGa thin film stack structures with precise magnetic property measurements. This initiative is crucial for advancing technology to support strategic mission objectives and enhance defense capabilities through innovative materials research and development. Interested parties are encouraged to submit their responses to Ashley Briseno at ashley.m.briseno.civ@us.navy.mil by the response deadline specified in the SAM posting, as there is no solicitation available at this time.
