Title: Scanning tunnel microscope having potential distribution measuring function
Inventor: KUSAKA TAKAO
IPC: G01R29/12
Filed: 1993-06-25
Abstract: PURPOSE:To accurately measure ruggedness and potential distribution in a very small area on the surface of a sample by applying an AC voltage as a bias voltage and finding the amplitude of the component of a tunnel current synchronous to the AC voltage. CONSTITUTION:When an AC voltage V1 from an oscillator 5 and voltage V2 from another oscillator 6 are applied across a sample 1 and probe 7, with the voltage V1 being applied as a bias voltage, a tunnel current It (=I1+I2) starts to flow. In addition multipliers 10 and 17 input a voltage proportional to a noise-superimposed component. The multiplier 10 outputs the component synchronous to a reference signal 1 among the sum signals of the current It noise, and signal 1 after converting it into a DC and the other component after converting it into an AC. A feedback circuit 13 only inputs the amplitude of the current I1 from which only the DC component is filtered 11 and a Z-axis driving signal accurately reflects the surface ruggedness of the sample 1. Of the components outputted from the multiplier 17, only the DC component is similarly filtered and only the amplitude of the current I2 is inputted to a voltage measuring circuit 20. As a result, the potential distribution map on the surface of the sample 1 is obtained by recording 21 the amplitude together with X- and Y-axis driving signals, namely, the position of the probe 7.

IPC: G11B5/712
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic metal powder for magnetic recording media and a painted type magnetic recording media using a magnetic metal powder superior in stability when used for a long time. SOLUTION: Gamma butyrolactone or its derivative is glued to a magnetic metal powder. These chemical compound may be glued to either magnetic metal powder on the market or the surface of the magnetic metal powder just after reduction under manufacturing process. Using the magnetic metal powder obtained by this, the magnetic paint is made, then the painted type magnetic recording medium is made. Glued by the gamma butyrolactone or its derivative, the activated point on the surface of magnetic metal powder loses activation. Therefore the chemical stability against oxidation of the magnetic metal powder is improved and the magnetic recording media well stable for saturation magnetization and residual magnetic flux density can be obtained.
