【摘要】 用交流电化学沉积方法在氧化铝模板中制备了三元合金Fe-Co-P非晶纳米线阵列。结果表明,纳米线的直径和钮化铝模板孔洞的直径相当,大约为40 nm。磁滞回线显示了纳米线具有很强的形状各向异性,平行于纳米线方向为易磁化轴。随着Co含量的增加,平行于纳米线方向的矫顽力和剩磁比在增加。穆斯堡尔谱显示了Fe原子的磁矩沿着纳米线方向。更多还原

【Abstract】 Arrays of Fe-Co-P amorphous nanowires were fabricated in anodic aluminium oxide templates by AC electrochemical deposition. The result shows that the nanowires are regular and uniform, about 40 nm in diameter. The magnetic hysteresis loop shows that the arrays of nanowires exhibit magnetic anisotro py that depends on the shape of each individual nanowire, and the easy axis is parallel to the nanowires. When the applied magnetic field is parallel to the wire axis, the coercivity and squareness of the nanowire arrays increase with increasing Co concentration. The Mossbauer spectrum demonstrates that the magnetic moments of the Fe atoms are approximately parallel to the wire axis.更多还原
