This Small Business Technology Transfer (STTR) Phase I research project will address the critical need for novel high-moment magnetic materials with improved corrosion resistance at the nanoscale for information storage and biosensor array applications. The innovative core of this Phase I work is the optimization of CoFeX alloys, where X is a noble metal, to achieve high corrosion resistance without compromising the magnetic moment or magnetically soft properties of the material and the production of electrodeposited sub-100nm CoFeX magnetic structures with verifiable mean magnetic moments above 2.4 Tesla and high corrosion resistance. Successful completion of this project will result in a stable fabrication process that will enable technology transfer to the manufacturing environment. The immediate impact of this research is to provide materials necessary to produce magnetic biosensors and transferable to the magnetic data storage industry. The broader impact of this work is to enrich the materials science and engineering of noble metal additives in magnetic alloy systems. Moreover, this research is expected to shed light on the corrosion of magnetic alloys and the transferability of the properties of electrochemically synthesized magnetic alloys to the nanoscale.

这项小型企业技术转移（STTR）第一阶段研究项目将解决对新型高矩磁性材料的关键需求，这些材料具有纳米级的抗腐蚀性，用于信息存储和生物传感器阵列应用。第一阶段工作的创新核心是优化CoFeX合金，其中X是一种高贵的金属，在不影响材料磁矩或磁软性能的情况下实现高耐腐蚀性，并生产电沉积的低于100nm的CoFeX磁性结构，可验证的平均磁矩超过2.4特斯拉，具有高耐腐蚀性。这个项目的成功完成将导致一个稳定的制造过程，这将使技术转移到制造环境。这项研究的直接影响是提供生产磁性生物传感器所需的材料，并可转移到磁性数据存储行业。这项工作的广泛影响是丰富磁性合金系统中贵金属添加剂的材料科学和工程。此外，该研究有望揭示磁性合金的腐蚀和电化学合成磁性合金的性能转移到纳米尺度。
