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.
