概要

• 論文の詳細を見る

• X-ray magnetic circular dichroism (XMCD) was measured for the ferromagnetic uranium monochalcogenides US and USe at U N_<4,5> absorption edges in the soft X-ray region. The obtained N_<4,5> XMCD signal of US was comparable to the M_<4,5> XMCD signal obtained in previous studies. From the sum-rule analysis of XMCD data, it was shown that the estimated ratios of orbital magnetic moment to spin magnetic moment |μ_L/μ_S| were almost the same for US and USe. The analysis of the XAS branching ratio indicated an increase in 5f electron occupation number from US to USe, which may suppress the increase in |μ_L/μ_S|.
