Abstract

Compounds containing Eu show a vast range of unique physical properties due to the interplay of electronic and magnetic properties, which can lead to a nontrivial electronic topology combined with magnetic order. We report on the growth of trigonal ([Formula: see text] space group) EuZnAs single crystals and on the studies of their structural, electronic and magnetic properties. A range of experimental techniques was applied including X-ray diffraction, electron microscopy, magnetic susceptibility, magnetization, heat capacity and Mössbauer spectroscopy in the study. We found that Eu has solely a 2+ valence state and its magnetic moments below T = 19.2 K form a canted antiferromagnetic structure, tilted from the basal plane.

摘要

由于电子和磁性特性的相互作用，含铕化合物表现出广泛的独特物理性质，这可能导致与磁序相结合的非平凡电子拓扑结构。我们报道了三角（[化学式：见正文]空间群）EuZnAs单晶的生长及其结构、电子和磁性性质的研究。在研究中应用了一系列实验技术，包括X射线衍射、电子显微镜、磁化率、磁化强度、热容量和穆斯堡尔光谱。我们发现铕仅具有2 +价态，并且其在T = 19.2 K以下的磁矩形成了从基面倾斜的倾斜反铁磁结构。
