Abstract

Magnetic state of the \(\textrm{EuFe}_2\textrm{As}_2\) single crystal was investigated by electron spin resonance (ESR). The ESR spectra of europium ions were registered in the temperature range from 250 to 4 K. To study the anisotropy, the in-plane angular dependences were investigated at temperatures of 15 K upon rotating a crystal around the c-axis. The data analysis shows that \(\textrm{EuFe}_2\textrm{As}_2\) is an antiferromagnet with an easy anisotropy plane. Moreover, the second-order easy magnetization axis is observed for each of the two types of magnetic domains related with structural twins arising from the tetragonal-to-orthorhombic crystal lattice transition.

ESR揭示\(\textrm{EuFe}_2\textrm{As}_2\)磁性结构特征

利用电子自旋共振(ESR)研究了\(\textrm{EuFe}_2\textrm{As}_2\)单晶的磁态。在250 ～ 4 K的温度范围内记录了铕离子的ESR谱。为了研究各向异性，在温度为15 K时，研究了晶体绕c轴旋转时的面内角依赖性。数据分析表明，\(\textrm{EuFe}_2\textrm{As}_2\)是一个具有易各向异性平面的反铁磁体。此外，在四方晶格向正交晶格转变产生的结构孪晶相关的两种磁畴中，每一种磁畴都观察到二阶易磁化轴。
