本文报道了用高温量热法直接测定的Mn、Fe、Co、Ni和Cu与全部三价稀土金属二元合金的混合标准曲线。在沿着R和过渡金属（TM）行的变化中建立了几个参数。特别是，逐渐增长的TM-R相互作用（负值的混合双折射率）沿着R系列中观察到的所有系统中，与明显的异常发现Ce的合金与Co和Ni。Mn → Fe → Co → Ni ← Cu的趋势，在不同的稀土合金中建立了不同的相互作用。发现不同原子沿着R行的相互作用的生长按照方案Cu → Mn → Fe → Ni → Co增加。
The standard enthalpies of mixing measured directly by high temperature calorimetry are reported for binary alloys of Mn, Fe, Co, Ni and Cu with the whole range of trivalent rare earth (R) metals. Several regularities in the variations along R and transition metal (TM) rows were established. In particular, gradual growth of TM-R interactions (negative values of mixing enthalpies) along the R series was observed in all systems, with distinct anomalies found for Ce in alloys with Co and Ni. Mn → Fe → Co → Ni ← Cu trends in varying the interactions were established in alloys with different rare earths. The growth in interactions of dissimilar atoms along the R row was found to increase according to the scheme Cu → Mn ≈ Fe → Ni → Co.
