Key words:  Co/C multilayer      annealing      period expansion.      Received:  18 October 1996      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1996/V32/I10/1068 1SpillerE,StearnsDG,KrumreyMJApplPhys,1993;74:1072SpillerE,WilczynskiJ,StearnsDG,GolubL,NystromG．ApplPhysLett,1992;61:14813SpillerE．OptEng,1990;29:6094KrishnanR,GuptaHO,SellaC,KaabouchiM．JMagnMagnMater,1991;93:1745ZieglerE,LepetreY,SchullerIK,SpillerE．ApplPhysLett,1986;48:13546MiedemaAR,deChatelPF,deBeerFR．Physica,1980;B100:19317JiangZ,DupuisV,VidalB,RavetMF,PiecuchM．JApplPhys,1992,72:9318BeemanD,SilvermanJ,LyndsR,AndersonMR．PhysRev,1984,B30:8709DillonRO．WoollamJA,KatkanantV．PhysRev．1984;B29:348210DupuisV,RavetMF,TeteC,PiecuchM,LepetreY,RivoiraR,ZieglerE．JApplPhys,1990;68:514611LepetreY,ZieglerE,SchullerIK,RivoiraR．JApplPhys,1986;64:2301 [1] CHEN Xueshuang, HUANG Xingmin, LIU Junjie, LV Chao, ZHANG Juan.
