摘要：PURPOSE:To clearly measure the recording state of a vertical magnetic recording medium by using a cantilever consisting of a probe and a leaf spring where a hard magnetic thin film is formed at the tip as the cantilever for magnetic force microscope. CONSTITUTION:A stainless steel foil 1 is machined in the shape of a leaf spring 2 and then a probe 3 is adhered to the tip of the leaf spring 2. In the probe 3, iron/cobalt alloy thin film 5 is formed on the surface of an iron probe 4 which is machined in needle shape by performing electrolytic polishing of iron wire by the electrolytic plating method. The iron/cobalt alloy is a hard magnetic material and has a large coercive force so that the direction of magnetization of the probe 3 is constantly maintained to be fixed and attraction and repulsion operate according to sample magnetization direction for the probe 3 when the sample 3 is brought closer to the sample surface and scans the sample surface in parallel. When the probe 3 is moved slightly up and down by a piezoelectric element and scans the sample surface in parallel in this state, the probe 3 is controlled in upper position when the magnetization is in the same direction. On the other hand, when the magnetization is in opposite direction, the probe 3 is controlled in lower position. It is changed into an image, thus measuring the magnetization distribution of the sample.
