    • Above the sample (9) having magnetic domains, a distribution of magnetic force in a measurement plane (91) is obtained as a magnetic force image with use of a MFM, an auxiliary magnetic force image is obtained by performing measurement in a measurement plane (92) away from the measurement plane (91) by a minute distance d, and a difference between them is divided by the minute distance d to obtain a magnetic force gradient image. The magnetic force image and the auxiliary magnetic force image are Fourier transformed and substituted into a three-dimensional field obtaining equation derived from a general solution of the Laplace equation, and the three-dimensional field indicating the magnetic force is obtained with high accuracy. A state of the magnetic domains at the surface (93) of the sample (9) can be obtained with high accuracy by obtaining the three-dimensional field. The three-dimensional field obtaining method using the three-dimensional field obtaining equation can be used for various fields of magnetic, electric, temperature and gravity potential and so on satisfying the Laplace equation. The obtaining of the three-dimensional field can be extended to obtaining of an n-dimensional field having high-dimension.
    • 在具有磁畴的样品(9)上方,通过使用MFM获得在测量平面(91)中的磁力分布作为磁力图像,通过在测量平面中进行测量获得辅助磁力图像( 92)远离测量平面(91)微小的距离d,并且它们之间的差除以微小距离d以获得磁力梯度图像。 将磁力图像和辅助磁力图像进行傅里叶变换并代入由拉普拉斯方程的一般解导出的三维场获得方程,并且以高精度获得表示磁力的三维场。 通过获得三维场,可以高精度地获得样品(9)的表面(93)处的磁畴的状态。 使用三维场获得方程的三维场获取方法可以用于满足拉普拉斯方程的磁,电,温度和重力等各种领域。 可以将三维场的获得扩展到获得具有高维度的n维场。
