摘要

采用机械合金化方法合成了高质量的carfe4as4和EuCsFe4As4化学计量铁基超导体样品，并通过XRD相分析证实了样品的单相组成。carfe4as4和EuCsFe4As4的超导转变温度分别为35 K和34 K，转变宽度分别为5.4 K和2.5 K。根据我们的磁性测量，我们在样品中只发现了一个超导跃迁。

Synthesis of CaRbFe4As4 and EuCsFe4As4 Stoichiometric Superconductors by Mechanical Alloying

We synthesized by mechanical alloying high-quality polycrystalline samples of CaRbFe₄As₄ and EuCsFe₄As₄ stoichiometric iron-based superconductors with single phase composition confirmed by XRD phase analysis. The superconducting transition temperatures were 35 and 34 K, and the transition widths were 5.4 and 2.5 K for CaRbFe₄As₄ and EuCsFe₄As₄, respectively. According to our magnetic measurements, we found only one superconducting transition in the samples.
