顺磁性

In this kind of complexes, one or more diamagnetic atoms are between two paramagnetic metal ion.

在配合物中，两个顺磁性金属离子间需要间隔一个或多个抗磁性原子才能使相转移温度有一定程度的提高。

分别针对顺磁性和逆磁性流体，推导了热磁对流的磁浮升力。

At the normal state, porphyrin molecules do not have EPR signal. However, light excitation may cause a transition of porphyrin molecules from singlet to triplet. At the same time, the change from diamagnetism to paramagnetism occurred to porphyrin molecules. In this case, the two un-paired electrons are nearby each other and cause a strong interaction, giving EPH signal with sharp peak at g = 2.000. The g value increased with an increase in electron cloud density.

常态下卟啉分子没有EPR信号，在光的激发下，卟啉分子由原来的逆磁性分子变成顺磁性的激发三重态分子，这种激发三重态分子在分子轨道上具有两个未成对电子，这两个电子相距很近，彼此之间发生很强的相互作用而产生电子，它的g值随卟啉共轭体系平均电子云密度增大而变大。

Qualitative Discussion of Diamagnetism Paramagnetism and Ferro Magnetism.

磁性材料。定性讨论反磁性，顺磁性，及铁磁性。

Curie point isotherm is the temperature isotherm where ferromagnetic minerals in the rocks change from ferromagnetism into paramagnetism because the temperature increases to the Curie point. Below this isotherm, the rocks are thought to be almost non-magnetism because their temperature is higher than the Curie point. Sino-US two-ship expanding spread profiles eastern transect in 1985 and Sino-Japan Ocean Bottom Seismography profile in 1993 (OBS93) crossed the major structural belts and basins in the northeastern South China Sea.

Mineral magnetic parameters, including magnetic susceptibility, frequency dependent susceptibility, isothermal remanent magnetization, anhysteretic remanent magnetization, temperature-dependence of susceptibility, were measured on quartzite and surface soil derived from quartzite. The results in combination with the microscope observation indicated little magnetic mineral in quartzite but a few magnetite, maghemite, iron oxyhydroxides in surface soil. The magnetic grains were mainly superparamagnetic and stable single domain. Maghemite is secondary mineral formed in the process of pedogenesis.

Theoretical analysis shows that Faraday magnetooptical effect has the anisotropy, and Faraday rotation is depend not only linearly on the magnetization Min paramagnetic and ferromagnetic media or the sublatbee's magnetization Mi in ferrimagnetie and antiferromagnetie media, but also on the high-order terms of M or Mi.

理论分析表明，法拉第磁光效应具有各向异性特性；法拉第旋转不仅与顺磁性和铁磁性介质中的磁化强度M或反铁磁性和亚铁磁性介质中的次晶格磁化强度Mi的线性项有关，而且还应与M或Mi的高次项有关。

The second part was to test the appearance, ingredient analysis, surface potential, thermal conduction properties, and magnetism of the nano composite fluid prepared from the parameters. The experiment found that unoxidized particles, Ag, Cu, Fe, and Ni appeared round. If combined with oxygen in water as oxides, the nano particles would grow toward certain directions. In copper/iron nano composite fluid, FeO appeared cubic, Cu2O appeared coniferous. In silver/iron nano composite fluid, FeO was polygonal. In dielectric potential detection, the nano composite fluid was likely to aggregate and deposit, except for silver/iron set. In other sets, the pH of silver/cobalt nano composite fluid was 7, surface potential was 21.21mV; the pH for silver/nickel nano composite fluid was 6.5, surface potential was 21.04mV; the pH for copper/iron nano composite fluid was 7, surface potential was -30mV. The fluid particles of the three sets could all maintain suspension of 2 weeks or more. For thermal conduction, the silver/nickel, nano composite fluid showed the best thermal conduction. Under temperature of 30℃ fluid weight conduction of 0.4%, the thermal conduction increase was 26%. For magnetic detection, except for silver/iron nano composite fluid, the nano particles of other three sets were paramagnetic, and all four sets were soft magnetic nano composite materials.

第二部分。将由较佳制备参数所产出的奈米复合流体，进行形貌外观、成分分析、表面电位及热传导性质实验与磁性检测；在奈米颗粒的形貌部分，经实验发现Ag、Cu、Fe、Ni等未氧化的颗粒皆呈现近似圆形，而若与水中的氧结合形成氧化物，奈米颗粒则会朝特定方向成长，在铜/铁奈米复合流体中FeO为四方体结构、Cu2O的颗粒是针叶状，在银/铁奈米复合流体中FeO则为多边形结构；而介面电位检测方面，结果显示经本制程所产出的奈米复合流体除银/铁奈米复合流体这一组较容易聚集沉淀外，其他三组中银/钴奈米复合流体的pH值为7，表面电位为21.21mV，银/镍奈米复合流体的pH值6.5表面电位为21.04mV而铜/铁奈米复合流体的pH值为7时表面电位约在-30mV，且此三组流体颗粒皆能维持悬浮性2周以上，悬浮性较佳；热传导实验部分，四组奈米复合流体中以银/镍奈米复合流体在增进热传上效果最佳，在温度30℃及流体重量浓度0.4﹪条件下热传导系数增进达26﹪；磁检测方面，除了银/铁奈米复合流体外，其他三组奈米颗粒皆属顺磁性，且这四组奈米复合材料都是属软磁性。

The results show that with the increase of deformation strains and thinning of Fe-Cr fibers, the saturation magnetization are about 140 A·m2/kg constantly, and the remanent magnetism and coercivity increase gradually.The magnetic properties of Fe-Cr fibers are invariant when the Fe-Cr fibers were preserved in absolute alcohol or air for more than 1 a. After Fe-Cr fibers heated in air at temperature higher than 300 ℃ for 1 h, the Fe-Cr fibers transform from ferromagnetic α-solution to paramagnetic2O3, and the saturation magnetization of samples decreases remarkably. With the increase of deformation strains, the thermal stability of thinner Fe-Cr fibers decreases.

结果表明：随着变形量的增大和Fe-Cr纤维的细化，纤维的饱和磁矩基本恒定(约140 A·m2/kg)，而剩磁和矫顽力则逐渐增加； Fe-Cr纤维在无水乙醇和空气中储存一年以上，磁性基本保持不变； Fe-Cr纤维在空气中经300 ℃以上加热1 h后，逐渐由铁磁性的α-固溶体转变为顺磁性的2O3，饱和磁化强度显著下降；且随着变形量的增大，较细Fe-Cr纤维的热稳定性较差。

Curie point: The temperature at which a material loses its ability to retain magnetism, that is, changes from ferromagnetic to paramagnetic behavior.
