Enhancing the Capabilities for Characterization of Magnetic Materials at the University of California, Davis

加州大学戴维斯分校的Verosub研究人员最近开发了一种技术，该技术使用部分磁滞曲线来确定材料中的磁性分布。该方法比使用主要磁滞回线或传统的磁测量方法更详细地探索磁行为的微观机制。这项重大研究仪器拨款将为具有高磁场和低温能力的交变磁场梯度和振动样品磁强计组合提供资金。该仪器将允许研究人员在比目前更广泛的条件下观察更多种类的材料。这些增强的实验能力将导致在古地磁学、岩石和矿物磁学和环境磁学方面取得新的进展，以及对凝聚态物理，特别是合成磁性材料和磁性纳米结构的新见解。

The method probes the microscopic mechanisms of magnetic behavior in greater detail than is possible with major hysteresis loops or with conventional magnetometry. This Major Research Instrumentation grant will provide funding for a combined Alternating Field Gradient and Vibrating Sample Magnetometer with high magnetic field and low temperature capabilities. The instrument will allow researchers to look at a much wider variety of materials under a much broader range of conditions than can be done presently. These enhanced experimental capabilities will lead to new advances in paleomagnetism, rock and mineral magnetism and environmental magnetism as well as new insights into condensed matter physics, particularly synthetic magnetic materials and magnetic nanostructures.***
