高压和高温被用来合成以前未知的化合物PrFe 2，NdFe 2和YbFe 2。这些化合物均为立方MgCu2型结构，晶格常数分别为7.467，7.452和7.239.讨论了4f成键和尺寸效应在LFe2化合物（L=镧系元素）形成中的相对重要性。
High pressures and temperatures were used to synthesize the previously unknown compounds PrFe 2, NdFe 2 and YbFe 2. These compounds have the cubic MgCu 2-type structure with lattice parameters 7.467, 7.452 and 7.239 A respectively. The relative importance of 4f bonding and size effects in the formation of LFe 2 compounds (L= lanthanide) is discussed.
