Effect of Ag Layer Thickness on Microstructure andMagnetic Properties of Ag/Fe/Ag Thin Films
摘要/Abstract
室温下,利用直流对靶磁控溅射设备制备了Ag(x)/Fe(35nm)/Ag(x)系列薄膜,x=1,2,3,4nm.利用扫描探针显微镜(SPM)观测了样品的表面形貌及磁畴结构,应用X射线衍射仪(XRD)分析了样品的晶体结构,通过振动样品磁强计(VSM)测量了样品的磁特性.研究表明,非磁性Ag层厚度对Ag/Fe/Ag系列薄膜的微结构和磁特性有很大的影响.SPM观测显示,随Ag层厚度增加磁畴尺寸呈现先减小后增加的趋势.VSM结果显示,矫顽力的变化与磁畴尺寸的变化趋势是一致的,x=3nm时,垂直膜面矫顽力达到最大.
Ag(x)/Fe(35 nm)/Ag(x)thin films were prepared by DC facing-target magnetron sputtering at room temperature,the thickness of Ag layer x =1,2,3,4,5nm.The morphologies and magnetic domain structureswere observed by scanning probe microscope (SPM),the cry stal structures were analyzed by X-ray dif fraction(XRD),the magnetic properties were measured by vibrating sample mag netometer (VSM).It has beenfound that the microst ructure and mag netic properties of Ag/Fe/Ag films depend st rongly on the thickness of Agnonmagnetic layer.SPM show s the size of mag netic domain decreases and then increases with increasing Ag layerthickness.The VSM shows that the change of coercivity consistents with the change of magnetic domain size.
