我们表明，具有 MgAgAs 型结构的 RMSn 化合物具有较低的伽马值，这与 E(F) 处存在间隙一致。 当 M = Co 时观察到较高的值，特别是对于铁磁体 TiCoSn。 金属多数自旋能带和半导体少数自旋能带同时存在，解释了磁有序性。
We show that RMSn compounds with MgAgAs-type structure have low gamma values in agreement with the existence of a gap at E(F). Higher values are observed for M = Co in particular for TiCoSn which is a ferromagnet. A metallic majority-spin band and semiconduction minority-spin band are existing simultaneously explaining the magnetic ordering.
