Abstract：The kinetic behaviour of the reversible magnetic permeability relaxation inthe amorphous(Fe_(0.1)Ni_(0.35)Co_(0.55))_(78)Si_8B_(14)and Fe_(40)Ni_(38)Mo_4B_(18)alloys has been inves-tigated under the temperature range of 0—300℃.The isochronal relaxation spec-tra were found and each of them is characterized by three relaxation peaks.Thedistributions of the relaxation times and the most probable values of the activationenergies were estimated.The effect of the annealing and rather slow cooling aboveCurie temperature on the kinetics of relaxation was also studied preliminarily.Sincea quite similar behaviour was observed on these two alloys with substantiallydifferent compositions,it is believed that the magnetic permeability relaxation ismainly resulted from the local motion of elemental mobile anisotropic structuraldefects and their compositional effect seems to be of minor importance. 收稿日期: 1985-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 张延忠 程东 张东平 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I3/99 1 张延忠;金慧娟,金属学报,20(1984) ,B78． 2 Matsuyama,T.;Ohta,K.;Kajiura,M.;Teranishi,T.,Jpn.J.Appl.Phys.,19(1980) ,55． 3 Nose,M.;Esashi,K.;Kanehira,J.;Ohnuma,S.;Shirakawa,K.;Masumoto,T.,Proc.4th Int.Conf.on Rapidly Quenched Metals,Vol.1,Eds.Masumoto,T.;Suzuki,K.(?)IM,1982,p.1191． 4 Mizoguchi,T.;Hatta,S.;Akiyama,K.;Maeda,K.;Takayama,S.,ibid.,p.1195． 5 Egami,T.,J.Magn.Magn.Mater.,31-34(1983) ,1571． 6 Phillips,D.L.,J.Assoc.Comput.Mach.,9(1962) ,84． 7 Hesse,J.;Rübartsch,A.,J.Phys.,E7(1974) ,526． 8 Kronmüller,H.,Philos.Mag.,B48(1983) ,127． 9 Kronmüller,H.,J.Magn.Magn.Mater.,41(1984) ,366． 10 Egami,T.;Maeda,K.;Vitek,V.,Philos.Mag.,A41(1980) ,883． 11 Srolovitz,D.;Maeda,K,;Vitek,V.;Egami,T.,Philos.Mag.,A44(1981) ,847． 12 Egami,T.;Srolovitz,D.,J.Phys.,F12(1982) ,2141． 13 Allia,P.;Soardo,G.P.;Vinai,F.,J.Magn.Magn.Mater.,31-34(1983) ,1527． 14 Allia,P.;Vinai,F.,Phys.Rev.,B26(1982) ,6141． 15 Allia,P.;Beatrice,C.;Schneider,J.,J.Magn.Magn.Mater.,42(1984) ,148． 16 Allia,P.;Sato Turtelli,R.;Vinai,F.;Riontino,G.,Solid State Commun.,43(1982) ,821． 17 张延忠,金属学报,20(1984) ,B195． 18 Chambron,W.;Chamberod,A.,Solid State Commun.,35(1980) ,61 No related articles found!
