    • A magnetic force microscope capable of measuring the absolute value of a magnetic field with high resolution without causing a change in magnetization state of the probe. The magnetic force microscope includes a cantilever, a probe, a displacement detector that detects a displacement of the probe, a specimen carrier, and various transfer units. The magnetic force microscope that measures an undulation distribution as well as a magnetic field distribution on the surface of a specimen placed on the specimen carrier is further provided with a magnetic-field impress-unit that impresses a magnetic field to the probe, and an output of the magnetic-field impress-unit is controlled such that a magnetic force impressed onto the probe 5 is turned zero to thereby measure a magnetic field distribution on the surface of the specimen.
    • 能够以高分辨率测量磁场的绝对值而不引起探针的磁化状态变化的磁力显微镜。 磁力显微镜包括悬臂,探针,位移检测器,其检测探针的位移,试样载体和各种转移单元。 测量放置在试样载体上的试样表面上的波动分布以及磁场分布的磁力显微镜还设置有向探针施加磁场的磁场印迹单元,以及输出 控制磁场印迹单元的位置,使得施加到探针5上的磁力变为零,从而测量样本表面上的磁场分布。
