在这里，我们提出了线性偏振相关的软X射线吸收光谱数据在CeOsAl和CeFeAl的Ceedges。尽管在非弹性中子散射中看到的强烈的杂化betweenand传导电子和自旋间隙的存在，我们能够确定结合我们的光谱数据与磁化测量的晶体场基态波函数。结果定量解释了CeOsAl中沿易磁化轴方向的有序磁矩和磁矩沿着方向的测量结果。
Here we present linear-polarization-dependent soft x-ray absorption spectroscopy data at the Ceedges of CeOsAland CeFeAl. Despite the strong hybridization betweenand conduction electrons and the existence of spin gaps as seen in inelastic neutron scattering, we were able to determine the crystal field ground state wave functions by combining our spectroscopy data with magnetization measurements. The results quantitatively explain the small ordered moment alongand the measured magnetic moment along the easyaxis in CeOsAl.
