  摘 要:选取脉宽激光器沉积物工艺在蓝黄宝石(α-Al2O3)衬底上制作了不同的Mn参杂盐盐浓度的ZnO复合膜.测试然而意味着,合适的盐盐浓度的Mn的掺人,有帮助于ZnO:Mn复合膜(002)种子发芽而不造成Mn的腐蚀物,时候,所有的的复合膜均体流露出了空调温度铁永久磁铁.随着时间的推移Mn含铁的新增,复合膜光学复合膜带隙红移,相当于的Mn阳化合物电势移转跃迁消化吸收慢慢的提高,磁化难度慢慢的缩小.测试然而支持软件复合膜的铁永久磁铁起发源于替位的Mn阳化合物彼此的长程铁磁互相影响,Mn阳化合物新增以至于的平均磁矩缩小,可归因于附近的Mn阳化合物规格的新增促使的反铁磁影响提高,相相当于的sp-d交換影响慢慢的新增.   重点词:Mn掺入ZnO;sp-d交換;铁磁特征参数   总类号:TB7 参考文献广告码:A   新闻稿件识别码:1672-7126(2008)增刊-022-04   规范期刊论文:   [1]Wan Q,Li Q H,Chen Y J,et al.Fabrication and ethanol sensing characteristics of ZnO nanowire gas sensors[J].Appl.Phys Lett.,2004,84(18):3654   [2]Dietl T,Ohno H,Matsukura F,et al.Science,2000,287:1019   [3]Oiwa A,Slupinski T,Munekata H.Control of magnetization reversal process by light illumination in ferromagnetic semiconductor heterostructure p-(In,Mn) As/GaSb[J].Appl.Phys.Lett.,2001,78(4):518   [4]Ueda K,Tabata H,Kawai T.Magnetic and electric properties of transition-metal-doped ZnO films[J].Appl.Phys.Lett.,2001,79(7):988   [5]Sharma P.Nat.Mater.,2003,2:673   [6]Change V Q,Wang D B,Luo X H,et al.Synthesis,optical,and magnetic properties of diluted magnetic semiconductor Zn1-xMxO nanowires via vapor phase growth[J].Appl.Phys.Lett.,2003,83:4020   [7]Ankiewicz A O,Carmo M C,Sobolev N A,et al.Electron paramagnetic resonance in transition metal-doped ZnO nanowires[J].J.Appl.Phys.,2007,101:024324   [8]林益梅,叶志镇,陈兰兰,等.ZnO塑料膜的缺点的新进展情况[J],进口真空生物学与新技术学报,2006,26(5):385-391   [9]Fukumara T,Jin Z,Ohtomo A,et al.An oxide-diluted magnetic semiconductor:Mn-doped ZnO[J].Appl.Phys.Lett.,1999,75:3366   [10]Bylsma R B,Beeker W M,Kossut J,et al.Dependence of energy gap on x and T in Zn1-xMxSe:The role of exchange interaction[J].Phys.Rev.B,1986,33:8207   [11]Mi W B,Bai H L,Liu H,et al.Miernstructure,magnetic,and optical properties of sputtered Mn-doped ZnO films with high-temperature ferromagnetism[J].J.Appl.Phys.,2007,101:023904   [12]Grimmeiss H G,Oxren C.Identification of deep centers in ZnSe[J].J.Appl.Phys.,1977,48:5122   [13]Kim K J,Park Y R.Spectroscopic ellipsometry study of optical transitions in Zn1-xMxO alloys[J].Appl.Phys.Lett.,2002,81:1420   [14]Yoo Y Z,Fukumura T,Jin Z W,et al.ZnO:CoO sofid solution thin films[J].J.Appl.Phys.,2001,90:4246   [15]Ivill M,Pearton S J,He Y W,et.al.Magnetization dependence on cartier doping in epitaxial ZnO thin films co-doped with Mn and P[J].J.Appl:Phys.,101,2007:123909   [16]Iusan D,Sanyal B,Eriksson O.Theoretical stndy of the magnetism of Mn-doped ZnO with and without defects[J].Phys.Rev.B,2006,74:235208   [17]Neal J R,Behan A J,Ibrahim R M,et.al.Room-Temperature Magneto-Optics of Ferromagnetic Transition-Metal Doped ZnO Thin Films[J].Phys.Rev.L,2006,96:197208   [18]Szczyko J,Mac W,Twardowski A.Antiferromagnetic p-d exReview B,1999,59:12935
