Origin of PSD Behavior II: Hysteresis Measurements and Domain Observations of Small Single Particles

岩石磁学研究进入了一个新的高- 敏感性分析，其中有可能解开 在单个磁性颗粒水平上的磁性物理学。 的 PI将做一系列实验来研究磁畴行为 和磁滞回线的单个粒子，使用磁- 光学克尔效应和交变力磁力计。 两 这项工作的主要目标是：1：确定是否 大颗粒集合的行为由下式很好地表示： 组成集合体的平均颗粒的行为。 2.到 提取微物理数据，这些数据对于理解 单个颗粒的滞后行为。

Rock magnetic studies have entered a new phase of high- sensitivity analysis, in which it is possible to unravel the physics of magnetism at the level of single magnetic grains. The PI will do a suite of experiments to study magnetic domain behavior and hysteresis loops of single particles, using the magneto- optical Kerr effect and an alternating force magnetometer. The two primary goals of this work are: 1: To determine whether the behavior of a large assemblage of particles is well-represented by he behavior of an average grain making up the assemblage. 2. To extract microphysical data that are critical to understanding the hysteresis behavior of single particles.
