The broader impact/commercial potential of this project is through providing a sensitive, robust, room temperature operating magnetometer. Magnetometers are among the most widely used instruments in a variety of applications including healthcare, transportation safety, food contamination monitoring, and homeland security. In fact, the growing need for magnetic field sensors manifests itself in the $1.6 billion global market with a fast-growing medical segment. As for today, the maximum sensitivity is provided by the Superconducting Quantum Interference Devices. The high sensitivity is critically important for medical applications. However, this high sensitivity can be achieved in the superconducting devices only at cryogenic temperatures. The proposed magnetometer based on spin wave interferometer combines high sensitivity with room temperature operation. This combination provides a great improvement in healthcare by reducing the cost of equipment, in transportation safety enhancement by providing more accurate traffic control, and in food safety monitoring by detecting small concentrations of heavy metals. It will be of great benefit to society to have a magnetometer combining the high sensitivity of superconducting devices and room temperature operation.This Small Business Innovation Research (SBIR) Phase I project addresses the need for sensitive and room temperature operating magnetic field sensors by providing a magnetometer based on spin wave interferometer. There are different types of magnetic sensors available on the market. As of today, the maximum sensitivity up to attoTesla is provided by the Superconducting Quantum Interference Devices. However, this high sensitivity can be achieved only at cryogenic temperatures. The latter makes superconducting magnetometers expensive and limits its practical application. The proposed magnetometer is based on spin wave interference and free of constraints inherent in superconducting devices. The research objectives encompass the development and demonstration of a compact, non-expensive magnetometer with up to attoTesla sensitivity operating in a temperature range from cryogenic to 560 K. The outcomes of the proposed research will have an impact on commercial, defense and homeland security applications that need increasingly precise and robust magnetic sensors. The development of compact and high-sensitive magnetometer will be relevant to bio-sensing and bio-medical applications as well.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目更广泛的影响/商业潜力是通过提供一个灵敏、坚固、室温工作的磁力计。 磁力计是各种应用中使用最广泛的仪器之一，包括医疗保健，运输安全，食品污染监测和国土安全。事实上，对磁场传感器日益增长的需求体现在16亿美元的全球市场上，医疗领域快速增长。至于今天，超导量子干涉器件提供了最高的灵敏度。高灵敏度对于医疗应用至关重要。 然而，这种高灵敏度只能在低温下在超导装置中实现。 基于自旋波干涉仪的磁力计结合了高灵敏度和室温操作。这种组合通过降低设备成本在医疗保健方面提供了很大的改进，通过提供更准确的交通控制在运输安全方面提供了很大的改进，并且通过检测低浓度的重金属在食品安全监测方面提供了很大的改进。 小型企业创新研究（SBIR）第一期项目旨在提供一种基于自旋波干涉仪的磁力计，以满足对灵敏度高、可在室温下工作的磁场传感器的需求。 市场上有不同类型的磁传感器。到目前为止，超导量子干涉器件提供了高达阿托特斯拉的最大灵敏度。然而，这种高灵敏度只能在低温下实现。后者使得超导磁力计昂贵，并限制了其实际应用。所提出的磁强计是基于自旋波干涉和自由的超导设备中固有的约束。研究目标包括开发和演示一种紧凑、廉价的磁强计，其灵敏度可达阿托特斯拉，工作温度范围从低温到560 K。 拟议研究的结果将对商业，国防和国土安全应用产生影响，这些应用需要越来越精确和强大的磁传感器。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
