表面磁気光学Kerr効果(SMOKE)測定装置の作製
1989
A new measurement system of surface magnetooptic Kerr effect (SMOKE) has been developed. Combination of a polarization modulating method using electric detection and signal processing using a computer system provides very high sensitivity, 10-4 degrees, and a good signal to noise ratio. Moreover, electrical calibration using a Faraday cell makes it possible to measure the absolute value of a Kerr rotation angle of the order of 10-4 degrees. SMOKE hysteresis of 2-atomic layer of fcc-Co grown on a Cu(100) surface is successfully measured and its Kerr rotation angle is about 5×10-4 degrees.
