摘要： A coersive force distribution analyzing, apparatus applies a magnetic field substantially perpendicularly to a sample including a perpendicularly magnetically recordable magnetic thin film. While tow-dimensionally moving the sample, the coersive force distribution analyzing apparatus generates a magnetic flux detection signal in response to a leakage flux generated in a magnetic domain on a sample surface. The apparatus applies, to the sample, a first external magnetic field and a second external magnetic field respectively corresponding to a first threshold and a second threshold selected from a hysteresis characteristic corresponding to average magnetization of the sample. This results in first magnetic domain image data and second magnetic domain image data. The apparatus uses the first and second thresholds to binarize the first and second image data to generate a first coersive force distribution pattern corresponding to the difference between the binarized first and second image data.

摘要： In a coercive force distribution analysis device, a magnetic field is applied in substantially vertical direction to a sample having a magnetic thin film capable of recording vertical magnetism. A magnetic flux detection signal is generated in accordance with the leaking magnetic flux generated from a magnetic domain of the sample surface while the sample is horizontally moved. A first and a second external magnetic field corresponding to a first and a second threshold value selected from hysteresis characteristic corresponding to the sample average magnetization are applied to the sample so as to generate image data on a first and a second magnetic domain. The first and the second image data are subjected to digitization processing by the first and the second threshold value and the difference between them is generated as a first coercive force distribution pattern.
