Thermodynamic properties of FeS polymorphs (NERC grant NE/J010626/1, NE/J010626/2)

FeS polymorphs are of significant relevance to condensed matter physics and planetary science. In particular, they are thought to form the cores of Earth and Mars, which is suggested by their presence in many meteorites. Data are plain text files containing the relative volume expansion, molar heat capacity and molar entropy of the FeS phases at different pressures as a function of temperature. Research results based upon these data are published at https://doi.org/10.1016/j.jpcs.2017.07.033

FeS 多晶型在凝聚态物理学和行星科学领域具有重要意义。特别是，据信它们构成了地球和火星的核心，这一观点得到了众多陨石中存在 FeS 的证实。数据集包含纯文本文件，其中记录了不同压力下 FeS 相的相对体积膨胀、摩尔热容和摩尔熵随温度变化的函数关系。基于这些数据的研究成果已发表在 https://doi.org/10.1016/j.jpcs.2017.07.033 上。
