铁基超导体（FBS）及其超导性质的发现引起了人们极大的研究兴趣，并为基础和实验研究提供了非常丰富的物理高Tc族。1111（REFeAsO，RE =稀土）和1144（AEAFe 4As 4，AE = Ca，Eu; A = K，Rb）族是FBS中最重要的两个族，它们在掺杂和未掺杂的情况下分别提供58 K和36 K的高Tc。此外，这些族的晶体生长不是一个容易的过程，并且已经报道了在该方向上的大量努力。然而，制备高质量和合适尺寸的样品仍然具有挑战性。在这篇简短的综述中，我们将总结1111和1144族具有超导特性的材料，特别是多晶和单晶的生长，并对它们进行简短的比较，以了解发展问题。
The discovery of iron-based superconductors (FBS) and their superconducting properties has generated huge research interest and provided a very rich physics high Tc family for fundamental and experimental studies. The 1111 (REFeAsO, RE = Rare earth) and 1144 (AEAFe4As4, AE = Ca, Eu; A = K, Rb) families are the two most important families of FBS, which offer the high Tc of 58 K and 36 K with doping and without doping, respectively. Furthermore, the crystal growth of these families is not an easy process, and a lot of efforts have been reported in this direction. However, the preparation of high-quality and suitable-sized samples is still challenging. In this short review, we will summarize the growth of materials with their superconducting properties, especially polycrystals and single crystals, for the 1111 and 1144 families, and make a short comparison between them to understand the developmental issues.
