This Small Business Innovation Research Phase II project focuses on developing nanocrystalline soft ferromagnetic materials for various end use applications such as Electromagnetic Interference (EMI) suppression, magnetic bearings and inductors. Phase I clearly established the feasibility of producing these materials via a patented microwave plasma technique. In addition, these nanomaterials were consolidated to near theoretical densities using a patented plasma pressure compaction technique and the compacts exhibited high magnetic strength and low coercivity. During Phase II, the process will be to develop these materials for specific applications. Our Industrial partners will evaluate the produced materials to evaluate parameters, which are critical for transitioning the technology to an immediate useful product. In addition, an IP protection and various avenues to commercialize thetechnology will be sought.There are numerous applications for nanocrystalline soft magnetic materials with superior magnetic and mechanical properties and low core loss. This includes EMI prevention components, generators, transformers, data communication interface component, magnetic bearings (commercial high-performance applications in the domain of rotating machinery), magnetic recording heads, motors, sensors, and reactors. MMI plans to focus on three market segments including (1) EMI suppression (2) Magnetic Bearings and (3) Inductors.

这项小型企业创新研究阶段项目着重于开发用于各种最终用途应用的纳米晶体软铁磁材料，例如电磁干扰（EMI）抑制，磁轴承和电感器。第一阶段清楚地确定了通过专利的微波等离子体技术生产这些材料的可行性。另外，使用专利的等离子体压力压实技术将这些纳米材料合并到近乎理论密度，而紧凑型表现出很高的磁强度和低的矫正性。在第二阶段，该过程将是为特定应用开发这些材料。我们的工业合作伙伴将评估生产的材料以评估参数，这对于将技术转换为直接有用的产品至关重要。此外，将寻求IP保护和各种商业化thetechnology的途径。在具有出色的磁性和机械性能和低核心损失的纳米晶体软磁材料中有许多应用。这包括EMI预防组件，发电机，变压器，数据通信界面组件，磁性轴承（旋转机械域中的商业高性能应用），磁记录头，电动机，传感器和反应器。 MMI计划专注于三个市场领域，包括（1）EMI抑制（2）磁轴承和（3）电感器。
