Drastically different microstructures with modulated ferromagnetic and paramagnetic phases have been reported in the Co-based alloy films due to the grain boundary segregation or migration.To improve the magnetic properties of the Co-based film devices, the spatial arrangement of these magnetic induced phase separation should be controlled precisely.In order to investigate the formation mechanisms of the reported film morphologies in Co-based alloy films, we use a phase field model to simulate the microstructure evolution of the magnetic induced phase separation in polycrystalline Co-Cr, Co-Mo and Co-V binary alloy films.The mechanisms of the microstructure evolution of "honeycomb-like" structure,"chrysanthemum-like" structure and randomly modulated structure were investigated.

本实验中,Bi0.97Na0.03Fe1 xNixO3 (x=0,0.005,0.01,0.015)纳米颗粒采用溶胶凝胶法制得.由XRD测试可知,所制备的样品均为菱形扭曲的钙钛矿结构,磁性测量发现样品的磁性随Ni掺杂浓度的增加而增大.另外,还在Na, Ni共掺的样品中观察到了交换偏置现象,为了解释出现这种现象的原因,基于"反铁磁-铁磁"核-壳结构对样品作了细致的讨论.

本文采用溶胶凝胶法制备了Bi1-xTbxFeO3(x=0,0.01,0.03,0.05)纳米颗粒样品.X射线衍射(XRD)图表明制备的样品是菱方钙钛矿结构.Tb3+对Bi3+的替代使颗粒尺寸减小,同时也提高了系统的室温铁磁性.l％Tb掺杂的铁酸铋样品在50kOe的场下具有最大的磁矩1.73emu/g.带隙随着掺杂浓度增加而减小可能来自于颗粒尺寸的减小,样品的漏电流减小可以归于为氧空位的减少.

本文研究了三元、四元水盐体系的冰点和共晶点的测定和图形表达方法.以四元同离子体系K+//Cl-,SO42-,NO3--H2O和四元交互体系Na+,K+//SO42-,NO3--H2O及其相关的六个三元子体系为例,研究了其冰点、共晶点以及析盐规律,绘制出了共晶点温度-组成图.研究表明:(1)单盐溶液未达到饱和浓度时,冰点的温度随着浓度的增加而降低,大于饱和浓度时,单盐与冰共存的共晶点温度为定值,不随

It is well known that many aluminium alloys attain optimum properties due to the formation of age-hardening precipitates, most of which are metastable from the thermodynamic point of view.Those age-ha

TbMnO3是一种被广泛研究具有ABO3钙钛矿结构的多铁化合物.在其A或B位掺杂一些其它元素可以明显改变材料的多铁特性.先前的研究表明TbMnO3中位于A格位的Tb可以被Mn取代,这样可以获得组成为(Tb1-xMny)MnO3-的固溶体.初步研究表明其中x,y值不同的两个样品在低温下具有各自不同的磁结构.于是对整个固熔体进行了细致的研究.在低温下，这类化合物具有三种有序磁结构A(Tb的螺旋反铁磁有
