This research have been carried out to make clear real phenomena in magnetic materials from new view point of vector magnetic properties. We have found that the relationship between the magnetic field strength H-vector and the magnetic flux density B-vector in magnetic materials has a strong nonlinearity in both magnitude and phase angle in space, due to those oriented conditions. Thus we have pointed out that the magnetic properties should be defined as a vector relationship. In this research, the coercive force and the residual magnetic flux density were measured as a vector quantity, and the rnagnetostriction was expressed as a tensor. Furthermore, the Barkhausen signal was observed under rotating flux conditions. The detailed results were shown in each paper listed in this report. Here we will show you the contents of typical magnetic phenomena obtained through the two-dimensional magnetic measurements.(1) Two-dimensional (Vector) Magnetic Properties :- basic concept based on the v … More ector relationship between H- and B-vectors,- vector measurement methods under two-directional exciting conditions,- the E&S model for expression of vector magnetic properties to use in numerical simulations,- improved magnetic field analysis cords by using finite element method.(2) Distribution of Localized Vector Magnetic Properties in Magnetic Materials :- a special vector measurement sensor for localized measurement of magnetic properties,- localized two-dimensional magnetic properties influenced by grain and domain configuration in grain oriented silicon steel sheet,- inhomogeneous magnetic materials, which has magnetic and non-magnetic parts frequently.(3) Two-dimensional Magnetostriction :- the fundamental concept and the tensor theory,- a special strain gauge based on tensor method for measurements of the magnetostriction,- the alternating magnetostriction and the rotational magnetostriction,- three-dimensional behavior of the magnetostrictions.(4) Rotational Barkhausen Signal :- measurements of the rotational Barkhausen signal and its behavior,- new discovery of chaos phenomena in the rotational Barkhausen signals.

从矢量磁性的新观点出发，对磁性材料中的真实现象进行了研究。我们发现磁性材料中磁场强度h矢量与磁通密度b矢量在空间上的大小和相角都具有很强的非线性，这是由于取向条件的影响。因此，我们指出磁性应定义为一个矢量关系。在本研究中，将矫顽力和剩余磁通密度作为矢量进行测量，将磁致伸缩量表示为张量。此外，在旋转通量条件下观测了巴克豪森信号。详细的结果显示在本报告中列出的每篇论文中。在这里，我们将向您展示通过二维磁测量获得的典型磁现象的内容。(1)二维（矢量）磁性：——基于H矢量和b矢量之间的v…More矢量关系的基本概念，——双向激励条件下的矢量测量方法，——用于数值模拟的矢量磁性的E&S模型，——利用有限元法改进的磁场分析曲线。(2)磁性材料中的局域矢量磁性分布：—一种用于局域测量磁性的专用矢量测量传感器；—晶粒取向硅钢片中受晶粒和畴组态影响的局域二维磁性；—非均质磁性材料，通常具有磁性和非磁性部分。(3)二维磁致伸缩：-基本概念和张量理论，-一种基于张量法测量磁致伸缩的特殊应变仪，-交替磁致伸缩和旋转磁致伸缩，-磁致伸缩的三维行为。(4)旋转巴克豪森信号：-旋转巴克豪森信号及其行为的测量，-旋转巴克豪森信号中混沌现象的新发现。少
