0216346VerosubResearchers at UC-Davis have recently developed a technique that uses partial hysteresis curves to determine the distribution of magnetic properties within a material. 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.***

0216346Verosub加州大学戴维斯分校的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内磁性的分布。 该方法探测磁行为的微观机制更详细，比可能与主要的磁滞回线或与传统的磁力。 这项主要研究仪器拨款将为具有高磁场和低温能力的交变场梯度和振动样品磁强计提供资金。该仪器将使研究人员能够在比目前更广泛的条件下观察更广泛的材料。 这些增强的实验能力将导致古磁学，岩石和矿物磁学和环境磁学的新进展，以及对凝聚态物理学的新见解，特别是合成磁性材料和磁性纳米结构。
