Production of Magnetic Core Materials for Flux-Gate Magnetometers

SkyVision Sciences proposes to develop a process for fabricating Mo-Permalloy (6-81.3). The material is used as the core material in advanced magnetometers. Sourcing of high quality Mo-Permalloy has become increasingly difficult in the U.S. and worldwide making its replacement imperative. The Phase I effort will develop an electrolytic process for fabricating the Mo-Permalloy foils. The resulting foils will be measured for their magnetic, mechanical, and electrical properties including Barkhausen noise in order to optimize its functionality. The Phase II effort is envisioned to further improve and characterize the materials properties, scale the fabrication process, and provide material to NASA or its partners for fabricating a magnetometer with this new core material.
