Synthesis of europium-based crystals containing As or P by a flux method: attempts to grow EuAgP single crystals

Abstract

Europium-based materials are highly attractive due to their diverse range of physical properties. In these studies, we aimed to synthesize single crystals of the potentially topological semimetallic compound EuAgP, which up to this day has only been obtained in polycrystalline form. The flux method was employed for the syntheses, using fluxes such as: Bi, Sn, Pb, and In, in their various ratios. The purpose of using Bi flux was to try synthesizing an analog of EuAgAs single crystals, by fully substituting arsenic with phosphorus. The obtained crystals were characterized by x-ray diffraction and scanning electron microscopy. Despite many unsuccessful attempts to synthesize EuAgP single crystals, the study provides valuable insights into how different fluxes and their ratios influence the final synthesis product. It also underscores the complexity of designing analogs between arsenides and phosphides.
