1450791鲍尔斯这笔赠款支持在威斯康星大学密尔沃基分校（UWM）的超导岩石磁力计（SRM）的收购。 SRM将支持矿物和岩石磁学和古磁学的研究和研究培训。 岩石磁性的基础研究涉及自然矿物相获得磁性的物理机制，以及磁性被高保真记录或被环境因素改变的过程。 矿物磁性研究对许多工业应用中使用的改进材料的开发具有影响。 古地磁学研究解决地球的行为？的磁场通过地质时间，并有应用程序，以了解以前的位置，大陆在地球上，动力学行为和演变的地磁场和解释过去的环境条件，以更好地约束全频谱的地球？过去气候条件的变化范围。磁场相位如何获得磁化的基础研究和地球历史动力学的研究？根据岩石和天然火山玻璃中磁相记录的古强度观测， SRM将允许研究弱磁化材料和非常小的合成相，以满足直流超导量子干涉仪（DC-SQUID）对SRM的高灵敏度要求。 这种调查不能完成与现存的，但灵敏度低得多的旋转磁力仪在调查？的实验室。 该仪器将是威斯康星州的第一个此类仪器，并将支持区域和国际合作。 研究人员将开发仪器控制软件，使所有SRM测量结果能够以与社区矿物，岩石和古地磁数据库（MagIC）兼容的格式存档和输出。 SRM将支持学生的研究培训，重点是吸引代表性不足的学生到地球科学。 这种支持与NSF促进科学进步的使命是一致的，并可能通过促进学生在物理科学领域的职业培训来促进国家的繁荣和福利。

1450791BowlesThis grant supports acquisition of superconducting rock magnetometer (SRM) at the University of Wisconsin-Milwaukee (UWM). The SRM will support research and research training in mineral and rock magnetism and paleomagnetism. Fundamental studies in rock magnetism address the physical mechanisms responsible for the acquisition of magnetism by natural mineral phases and the processes through which that magnetism is either recorded with high fidelity or altered by environmental factors. Mineral magnetic investigations have implications for the development of improved materials for use in many industrial applications. Paleomagnetism studies address the behavior of the Earth?s magnetic field through geologic time and have application to understanding the former positions of continents on Earth, the dynamical behavior and evolution of the geomagnetic field and for interpreting past environmental conditions to better constrain the full spectrum of Earth?s past range of climate conditions.Fundamental studies of how magnetic phases acquire magnetization and studies of the historical dynamics of the Earth?s magnetic field based on paleointensity observations as recorded in magnetic phases in rocks and natural volcanic glasses will be supported. The SRM will allow studies of weakly magnetized materials and very small synthesized phases given to the high sensitivity of direct current superconducting quantum interference device (DC-SQUID) on the requested SRM. Such investigations cannot be accomplished with an extant but much less sensitive spinner magnetometer in the investigator?s laboratory. The instrument will be the first of its kind in the state of Wisconsin and will support regional and international collaborations. The investigator will develop instrument control software that will allow for all SRM measurements to be archived and output in a format compatible with a community mineral, rock and paleomagnetism database (MagIC). The SRM will support student research training with a focus on attracting underreprestented students to the geosciences. This support is congruent with NSFs mission of promoting the progress of science and may advance the national prosperity and welfare through promoting student training for careers in the physical sciences.***
