Title: Spin polarized scan type tunnel microscope as information detecting method and apparatus therefor
Inventor: KODAMA HIROKI
IPC: G01B15/00
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To accurately detect information on irregularities and magnetic information by reducing effect of noise. SOLUTION: Irradiation of circularly polarized light onto a probe is cut to scan a sample in one outgoing direction for detecting information on irregularities of the sample from a tunnel current measured. A separation distance between the probe and the sample is kept constant based on the information on the irregularities and the probe is irradiated with the circularly polarized light to scan the sample in one incoming direction for detecting magnetic information of the sample from the measured tunnel current. In this manner, the information on the irregularities alone is detected by cutting the irradiation of the circularly polarized light and thereafter, the probe is kept at a fixed distance from the probe to detect the magnetic information by the irradiation of the circularly polarized light.  Thus, even when the tunnel current is mixed with noises, the information on the irregularities can be completely separated from the magnetic information thereby achieving accurate detection of the information on the irregularities and the magnetic information separately.
