Mn1 +δ Sb的磁化强度随过剩Mn原子量δ的增加而线性减小。因此，过量Mn原子的磁矩被认为是反平行于规则的Mn磁矩。利用极化中子技术研究了Mn1.05Sb和Mn1.18Sb中过剩锰原子的磁极化。观察到过量Mn原子上没有磁矩。因此，磁化强度随δ增大而减小是由于规则位Mn原子磁矩的减小，这一结果表明过量Mn原子向规则位Mn原子提供电子。
The magnetization of Mn 1+δ Sb is known to decrease linearly with increase of the amount, δ, of the excess Mn atoms. Therefore, the magnetic moments of the excess Mn atoms were considered to be directed antiparallel to the regular site Mn moments. The magnetic polarization of the excess Mn atom is studied for Mn 1.05 Sb and Mn 1.18 Sb by using the polarized neutron technique. It is observed that there is no magnetic moment on the excess Mn atoms. Therefore the decrease of the magnetization with increasing δ comes from the decrease of the magnetic moment on the regular site Mn atoms, and this result suggests that an excess Mn atom donates electrons to the regular site Mn atoms.
