We measured magneto-optical (MO) Faraday rotation around the M2,3 edges (60—70 eV) of Ni film on 3W1B beam line of Beijing Synchrotron Radiation Facility (BSRF) in the soft X-ray region through a versatile polarimeter with mutilayer polarizers, which is mainly composed of polarizer, analyzer, sample frame, round NdFeB permanent-magnet and MCP detector. We used the reflective aperiodic molybdenum/silicon broadband multilayer polarizers as the polarizer and the analyzer in the versatile polarimeter, and obtained a series of Faraday rotation results in the 60—70 eV region. The results demonstrate that the Faraday rotation angles are obviously large around Ni M2,3 edges, the rotation angles are 179±019°(average rotation angle in parallel and antiparallel magnet fields) and -076±009°(average rotation angle in parallel and antiparallel magnet fields) at the energy 655 eV and 68 eV, respectively.
