To obtain various Ni/Mn orderings, we use a low-temperature synthesized method to modulate the Ni/Mn ordering of the ferromagnetic-ferroelastic La 2 NiMnO 6 compound, and the Ni/Mn ordering is estimated by the low-temperature saturation magnetism. The microstructures, crystal structures and magnetic properties are investigated, and the Landau theory are used to describe the form and magnitude of the coupling effects between Ni/Mn ordering and magnetic order parameters. It is predicted that the Ni/Mn ordering would be a strong coupling effect with the Curie transition temperatures if the La 2 NiMnO 6 sample stoichiometry is close.

B位点序对多功能La 2 NiMnO 6双钙钛矿中磁序的影响

为了获得各种Ni / Mn有序，我们使用一种低温合成方法来调制铁磁-铁弹性La 2 NiMnO 6化合物的Ni / Mn有序，并且通过低温饱和磁性来估计Ni / Mn有序。研究了微观结构，晶体结构和磁性能，并用Landau理论描述了Ni / Mn有序与磁有序参数之间耦合效应的形式和大小。据预测，如果La 2 NiMnO 6样品化学计量接近，则Ni / Mn有序与居里转变温度的耦合作用强。
