Room Temperature Ferromagnetism in V Doped ZnO Films

摘要/Abstract

摘要:

采用磁控溅射法在Si基底上制备了Zn1-xVxO系列薄膜样品,X射线衍射表明所有样品都具有纤锌矿结构,没有发现其他的衍射峰存在.研究发现,c轴晶格常数随着掺杂浓度的增加而增大.原子力显微镜测量表明样品中的颗粒分布均匀,没有发现团聚物.磁性测量表明,直接沉积的样品具有顺磁性,而经真空退火的所有样品都具有明显的室温铁磁性,且随着掺杂浓度的增加,样品的饱和磁化强度增加.

Abstract:

A series of V-doped ZnO films was prepared using the radio-frequency magnetron sputtering.No secondary phases and metal clusters were found in either sample.All of the Zn1-x V xO films were single phase and c-axis preferred o rientation.The XRD results also indicated a monotonic increased in the lattice constant with increasing V concentration.AFM showed sample particle size distribution of uniform,did not find clusters.Magnetization measurement showed that all samples annealed in the vacuum had the room temperature ferromagnetism.The saturation mag netization increased as the V concent ration increased in films.While the Zn0.95Ni0.05O thin films as grown only had paramagnetism.
