在1.8 ~ 293 K的温度范围内对（Pr, Nd, Gd, Tb, Dy, Er） ru2si2化合物的多晶样品进行了中子衍射和磁强测量。所有化合物都具有四方的thcr2si2型晶体结构。在低温下观察到（Pr, Nd） ru2si2在Pr和Nd亚晶格中的铁磁有序。磁矩与轴平行。对于（Tb, Dy, Er） ru2si2，磁自旋排列为线性横波模式。该静态矩波沿τ=[0,τ，0]的b轴传播，tbru2si2和dyru2si2在c轴极化，ErRu2Si2在b轴极化。从各向同性RKKY交换相互作用的角度讨论了观测到的磁有序方案。
Neutron diffraction and magnetometric measurements on polycrystalline samples of (Pr, Nd, Gd, Tb, Dy, Er)Ru2Si2compounds were performed in the temperature range between 1.8 and 293 K. All compounds have the tetragonal, ThCr2Si2-type crystal structure. In (Pr, Nd)Ru2Si2ferromagnetic ordering within the Pr and Nd sublattices is observed at low temperatures. The magnetic moment is parallel to thec-axis. For (Tb, Dy, Er)Ru2Si2the magnetic spin alignment is of a linear transverse wave mode. This static moment wave is propagating along theb-axis with τ=[0,τ,0] and is polarized in thec-axis for TbRu2Si2and DyRu2Si2and in theb-axis for ErRu2Si2. The observed magnetic ordering schemes are discussed in terms of isotropic RKKY exchange interactions.
