| Outline of Final Research Achievements |
We have developed a new magnetization-detecting type Electron Spin Resonance equipment by combining soft-X-ray magnetic dichroism and microwave resonant-cavities. For the estimate of the absolute sensitivity, we have also assembled a SQUID-ESR-equipment and evaluated the absolute value of the magnetization reversal in on-resonance states. We have succeeded in the observation of the XMCD signal change at the resonance state of a Fe-polycrystalline thin film. The XMCD signal change is found to be smaller than the estimated bulk magnetization reversal and the influence of the surface effect and/or the sample oxidization are examined. It is also turned out that the modulation detection is needed in XMCD measurement to suppress the baseline fluctuation, which limit the sensitivity of the system.
