MnPd 5Se，反CeCoIn 5型相的衍生物，从高温固相反应合成，通过X射线衍射确定结构，并结合磁性测量和中子粉末衍射（NPD）进行磁性表征。根据X射线衍射结果，MnPd 5Se以层状四方结构结晶，具有与CeCoIn 5，P4/mmm（No.123）相同的空间群。MnPd 5Se的磁性测量的基础上显示反铁磁有序约80 K。通过对300、50和6 K下的中子粉末衍射结果的分析，揭示了A型反铁磁结构。此外，随着温度的降低，观察到自旋取向旋转。Pd L3 X-射线吸收近边光谱MnPd 5Se半定性的结果与计算的状态密度支持一个名义上的0.2电子转移到Pd d轨道从硒或锰的化合物。沿着我们以前报道的MnT_5Pn（T = Pd或Pt; Pn = P或As）的发现，为研究具有强自旋轨道耦合效应的从铁磁性到反铁磁性的磁有序提供了一个可调系统。
MnPd5Se, a derivative of the anti-CeCoIn5-type phase, was synthesized from a high-temperature solid-state reaction, structurally determined by X-ray diffraction, and magnetically characterized with a combined magnetic measurement and neutron powder diffraction (NPD). According to the X-ray diffraction results, MnPd5Se crystallizes in a layered tetragonal structure with the same space group as CeCoIn5,P4/mmm(No. 123). MnPd5Se shows antiferromagnetic ordering around 80 K on the basis of the magnetic property measurements. An A-type antiferromagnetic structure was revealed from the analysis of neutron powder diffraction results at 300, 50, and 6 K. Moreover, a spin orientation rotation was observed as the temperature decreased. Pd L3X-ray absorption near edge spectroscopy results for MnPd5Se semiqualitatively correlate with the calculated density of states supporting a nominal 0.2 electron transfer into the Pd d orbital from either Se or Mn in the compound. The discovery of MnPd5Se, along with our previously reported MnT5Pn (T = Pd or Pt; Pn = P or As), provides a tunable system for studying the magnetic ordering from ferromagnetism to antiferromagnetism with the strong spin–orbit coupling effect.
