摘要:

提出了一种基于铁磁纳米结构中畴壁位移的新方法来吸引和感应单个纳米磁性粒子。我们建模和实验证明了该方法的可行性,使用各向异性磁阻装置由微米大小的方环坡莫合金设计的应用在磁存储。该检测概念可适用于生物分子识别,特别是单分子检测。

英文摘要:

A new approach based on the domain wall displacement in confined ferromagnetic nanostructures for attracting and sensing a single nanometric magnetic particles is presented. We modeled and experimentally demonstrated the viability of the approach using an anisotropic magnetoresistance device made by a micron-size square ring of Permalloy designed for application in magnetic storage. This detection concept can be suitable to biomolecular recognition, and in particular to single molecule detection.
