And in the ( t , h ) phase diagram there is a tricritical point , at which the two boundary lines of the paramagnetic and ferromagnetic regions merge )不为零。 ( t ， h )相图存在一个动力学三相点，顺磁区和铁磁区的边界线在这点开始汇合。
Carbon can promote the forming of carbide of fe3c mostly during the ma , while it seems that chromium makes amorphism easier . in addition , this paper also made a research on the milled powder forming technology , and presented some improvement methods 机械合金化过程中，碳元素可以促进以fe _ 3c为主的碳化物的析出，铬元素使粉末更趋向于非晶态转变，并使材料出现超顺磁现象。
Sem shows that the composite ferrite is like cotton and displays one by one , their diameters are about 50nm . vsm measurement in the strong magnetic field reveals that its coercive force and remanence are zero , that is , the product is supermagnetic one Sem表明复合型铁氧体呈“棉花状” ,颗粒排列紧凑,粒径在50nm左右;磁滞回线显示该铁氧体的矫顽力和剩磁均为零,证明其为超顺磁物质。
Long tr images show greater signal heterogeneity within the lesion core as a function of increasing te , probably because of the paramagnetic properties of hemorrhage : the main magnetic field is locally augmented by paramagnetic material and therefore a susceptibility difference is produced 长tr影像作为一种增加功能的te ，对病变中心显影更多的不均匀高信号区，这可能是源于出血产生的顺磁效应，即主要磁场的局部由于顺磁材料产生的磁性差异产生的一种结果。
However , a thorough understanding of the properties and mechanisms of these materials is still lacking . in this paper , we discuss the properties observed in two kinds of half - metallic granular systems , powders and polycrystalline materials and propose two models to explain the experimental results 我们建立了一个由直接隧穿电导和cotunneling电导组成的网络模型，采用有效介质理论对该网络进行处理，同时还考虑了小尺寸颗粒的超顺磁行为对磁电阻的影响。
