We report a successful synthesis of a ternary AlB-type intermetallic compound. The phase purity was obtained by fine-tuning the Pd : Ge ratio out of the idealized 1 : 3. Attempts to synthesize an Er analogue were not successful. We discuss the instability of the Er analogue based on the atomic size ratio and also suggest that the increased stability of HoPd Ge in the Pd-rich range likely stems from a combination of atomic size ratio, electronic, and entropic factors. The new HoPdGe compound is found to exhibit cluster glass behavior with a freezing temperature of ≈ 2.3 K.
我们报道了一种三元AlB型金属间化合物的成功合成。通过微调钯与锗的比例使其偏离理想化的1:3，获得了相纯度。合成铒类似物的尝试未成功。我们基于原子尺寸比讨论了铒类似物的不稳定性，并指出在富钯范围内HoPdGe稳定性增加可能源于原子尺寸比、电子和熵因素的综合作用。发现新的HoPdGe化合物表现出团簇玻璃行为，其冻结温度约为2.3K。
