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.

这个小型企业创新研究二期项目的重点是开发用于各种终端应用的纳米晶软铁磁材料，如电磁干扰抑制、磁轴承和电感器。第一阶段明确确定了通过专利微波等离子体技术生产这些材料的可行性。此外，利用专利的等离子体压实技术，这些纳米材料被巩固到接近理论密度，并表现出高磁场强度和低矫顽力。在第二阶段，过程将是开发这些材料的具体应用。我们的工业合作伙伴将对生产的材料进行评估，以评估参数，这对于将技术转化为即时有用的产品至关重要。此外，将寻求知识产权保护和各种技术商业化途径。纳米晶软磁材料具有优异的磁性和机械性能以及低磁芯损耗，具有广泛的应用前景。这包括EMI防止组件，发电机，变压器，数据通信接口组件，磁轴承（在旋转机械领域的商业高性能应用），磁记录磁头，电机，传感器和电抗器。MMI计划专注于三个细分市场，包括：(1)EMI抑制(2)磁轴承和(3)电感器。
