摘要
用脉冲强磁场测量法和奇点探测法 (SPD) ,研究了电弧炉熔炼方法制备的 1∶12型稀土过渡族金属间化合物Y(Fe1 -xCox) 1 1 .3Nb0 .7(x =0 .0 0 ,0 .0 5,0 .10 ,0 .15,0 .2 0 )多晶样品的室温磁特性 .研究结果表明 ,Y(Fe1 -xCox) 1 1 .3Nb0 .7系列化合物的室温 (30 0K)各向异性场Ba 和饱和磁化强度Ms,随Co含量的增加 ,都先增加后降低 .
The magnetic properties at room temperature of the polycrystal samples of Y(Fe 1- x Co x ) 11.3 Nb 0.7 compounds ( x =0.00,0.05,0.1.,0.15,0.20) prepared by Arc melting are investigated by pulse magnetic field(PMF) and singular point detection(SPD) measurement.The results of PMF measurement shows that the saturated magnetizations M s and the anisotropy fields B a of the Y(Fe 1- x Co x ) 11.3 Nb 0.7 at room temperature first increase with increasing x ,then decreases with further increasing x .
