This Small Business Innovation Research Phase I project proposes to develop anisotropic hard magnetic nanoparticles, based on rare earth transition metal compounds, with particle size in the range of 200 nm down to 100 nm. These nanoparticles will be consolidated by screen-printing into permanent magnet structures with dimensions to bridge the gap between the permanent magnet thin films (few nanometers to a few microns) and micromachined permanent magnets (larger than 500 microns). The anisotropic hard magnetic nanopowders consolidated by screen printing can serve as small permanent magnet structures with dimensions between ten microns to hundreds of microns for various devices. The improved magnetic properties will yield enhanced performance in these applications.This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).

该小型企业创新研究第一阶段项目提出开发基于稀土过渡金属化合物的各向异性硬磁纳米颗粒，粒径范围为200 nm至100 nm。这些纳米颗粒将通过丝网印刷被固结成永磁体结构，其尺寸为桥接永磁体薄膜（几纳米到几微米）和微机械加工的永磁体（大于500微米）之间的差距。通过丝网印刷固结的各向异性硬磁纳米粉末可以用作用于各种器件的尺寸在10微米至数百微米之间的小型永磁体结构。 该奖项由2009年美国复苏和再投资法案（公法111-5）资助。
