squareness ratio

Further magnetic measurements reveal that the nanotube array shows no anisotropy, the coercivity and squareness ratio are about 1 kOe and 0.37.

进一步的磁性测量表明，纳米管阵列无明显的各向异性，其矫顽力约1kOe，磁滞回线的方形度约0.37。

Higher coercive force and squareness ratio are attained as electroless Ni P alloy coating is used as a intermediate coating.

当以化学镀Ni－P合金作为中间镀层时，可获得较高的矫顽力和矩形比。

Electroless Co Ni P thin film as deposited is amorphous, having a lower coercive force and higher squareness ratio. Its magnetizable direction is perpendicular to surface of thin film.

化学镀Co－Ni－P薄膜镀态下为非晶态结构，Co－Ni－P薄膜的矫顽力较低，矩形比较高，其易磁化方向与膜面垂直。
