Pt_xCo_(1-x)(x=0.48~0.51)合金的磁性能和晶体结构 刘涛1,李卫1 (1.钢铁研究总院,北京,100081) 摘要:系统研究了等原子比附近不同Pt,Co原子比的PtCo合金的磁性能和晶体结构.采用电弧炉熔炼方式制备了原子比为.Pt_xCo_(1-x)(x=0.48~0.51)的合金,热处理后磁测量结果显示,随着Pt含量的增加,合金的剩磁逐渐减小,矫顽力逐渐增大.合金的X射线衍射结果表明:时效热处理后,随着Pt含量的增加,合金面心四方结构的有序相的c/a值逐渐减小,c/a值的减小增大了四方晶格结构的a与c方向的不对称性,使有序相的磁晶各向异性场增大,提高了合金的矫顽力. 关键词:PtCo合金; 磁性能; 晶体结构; 各向异性场; PtCo alloys; magnetic properties; crystal structure; anisotropy......
