我们报道了在准晶近似物中观察到的长程磁序，即，Cd 6 Tb，表明自旋玻璃不是二元近似的基态，但二十面体顶点上的局域自旋在24 K以下变成反铁磁有序的.这一结果与文献报道的由相同二十面体团簇组成的Cd-Mg-R准晶的类自旋玻璃行为相反。
We report the observation of a long-range magnetic order in a quasicrystalline approximant, i.e., Cd6Tb, demonstrating that a spin glass is not the ground state for the binary approximant but localized spins on the vertices of an icosahedron become antiferromagnetically ordered below 24 K. The result is in contrast to the spin-glasslike behaviors reported for Cd-Mg-R quasicrystals composed of same icosahedral clusters.
