通过 11B 和 27Al 核磁共振（NMR）测量研究了新型四方化合物 CeRu2Al2B 的磁性能。在顺磁状态下，奈特位移表现出很强的伊辛型磁各向异性。在铁磁有序状态下，根据 B 和 Al 位点的内部磁场大小，有序矩估计为 ≈1.8–1.85μB/Ce。这些结果强烈表明类伊辛铁磁基态源自 CeRu2Al2B 中的 Γ7(1) 基态。
The magnetic properties of the new tetragonal compound CeRu2Al2B have been investigated by11B and27Al nuclear magnetic resonance (NMR) measurements. In the paramagnetic state, the Knight shift exhibits a strong Ising-type magnetic anisotropy. In the ferromagnetic order state, the ordered moment is estimated to be ≈1.8–1.85µB/Ce from the magnitudes of the internal fields at the B and Al sites. These results strongly suggest that the Ising-like ferromagnetic ground state arises from the Γ7(1)ground state in CeRu2Al2B.
