The authors would like to appreciate the technical support of Dr. T. Gejo, UVSOR. They are grateful to Mr. K. Sakano for supplying the Sc/Cr multilayer analyzer. One of the authors (T.H.) is much obliged to Prof. T. Miyahara for his support of the MCD measurement at Photon Factory. This work was partly supported by the grand-in-aid for basic research (category C #09640387) from the Ministry of Education, Science, Sports and Culture, and by the Joint Studies Program (1997–1998, #583(H)) of the Institute for Molecular Science.

N2 - We constructed a polarimeter for Faraday rotation measurements around the M2,3 absorption edges in Ni, which consists of a transmission polarizer, a reflection analyzer and a magnetic circuit made of Sm-Co permanent magnet. The polarizer and analyzer are Al/YB6 multilayers. The polarizer is used to improve the degree of linear polarization of the monochromatized synchrotron radiation. The Faraday rotation angle around the M2,3 absorption edges in Ni was obtained reproducibly. The rotation angle was almost proportional to the sample thickness. This means that the Faraday rotation spectra are scarcely affected by surface pollution and reflect bulk properties. The measured value of rotation angle was somewhat larger than the value obtained by Kramers-Krönig transform of an MCD spectrum. This may be attributed to be the surface effect or insufficiency of the degree of circular polarization in MCD experiments.
