| Research Abstract |
We have successfully developed a new experimental technique of soft X-ray magnetic circular dichroism(XMCD) under pulsed high magnetic fields for the first time. The maximum magnetic field of 30 T has been achieved, which greatly exceeded the previous maximum field of 10 T generated by means of superconducting magnets. By applying the present technique, we can measure the partial magnetization originating from individual elements in alloys and compounds. The high-magnetic-field soft XMCD experiments have widely been applied to studies on a magnetic-field-induced valence transition material, a meta-magnetic material, rare earth based permanent magnets, and exchange bias film, so far.
