摘要

在大多数金属间铕化合物中，由于Eu2+与Gd3+是等电子的，Eu原子表现出具有高有效磁矩的二价氧化态。相比之下，三价金属间铕化合物极为稀少，文献中已知的例子不到20个。这篇综述总结了已知的二元和三元的例子，以及它们的晶体化学特性，以及它们的磁性和151Eu Mössbauer光谱行为。此外，还总结了表现出价相转变的化合物。

Trivalent europium – a scarce case in intermetallics

Abstract In most intermetallic europium compounds, the Eu atoms exhibit a divalent oxidation state with a high effective magnetic moment since Eu2+ is isoelectronic with Gd3+. Trivalent intermetallic Eu compounds, in contrast, are extremely scarce and under 20 examples are known to literature. This mini-review summarizes the known binary and ternary examples along with their crystal-chemical peculiarities as well as their magnetic and 151Eu Mössbauer spectroscopic behavior. Additionally, compounds that exhibit valence phase transitions are summarized.
