论文摘要
我们报告了抗抗铁磁剂到反115型MNPT $ _ {5-x} $ pd $ _x $ p（$ x $ = 1，2，2.5，3，4和5）的磁变化，并发现了一个新的稀有稀有的Ferromagnet $ _-5 $。使用高温固态方法合成家族化合物，并表征在抗蛋白质$ _5 $中结晶，其空间组P4/mmm具有二维分层结构特征。磁性测量值表明，从MNPT的倾斜A型抗铁磁铁中排序的化合物$ _5 $ P $ _5 $ P以高于室温的超过室温，并在MNPD $ _5 $ p的不同程度上以不同程度的胁迫和磁性矩来减少旋转孔孔偶联。与151个MN家族（PT/PD）$ _ 5 $（P/AS）相比，已经分析了MNPT $ _ {5-X} $ PD $ _X $ P的结果，以了解复杂的结构 - 磁性关系。
We report the magnetic changes from canted antiferromagnetic to ferromagnetic orderings in anti-115-type MnPt$_{5-x}$Pd$_x$P ($x$ = 1, 2, 2.5, 3, 4, and 5) and the discovery of a new rare-earth-free ferromagnet, MnPd$_5$P by both theoretical prediction and experimental investigation. The family compounds were synthesized using high temperature solid state method and characterized to crystalize in the anti-CeCoIn$_5$ type with the space group P4/mmm exhibiting a two-dimensional layered structural feature. The magnetic property measurements indicate that the compounds ordered from canted A-type antiferromagnet in MnPt$_5$P to ferromagnet above the room temperature with varying degrees of coercivity and magnetic moments in MnPd$_5$P by reducing the spin orbital coupling. The results of the MnPt$_{5-x}$Pd$_x$P have been analyzed in comparison to the other candidates of the 151 family of Mn(Pt/Pd)$_5$(P/As) to understand the complex structure-magnetism relationships.
