论文摘要
具有总角动量J = 2的重离子的立方双钙晶可以表现出一个唯一的磁性态，由孤立的八杆和块状铁型磁性表现为缩影。它存在于陈型汉密尔顿人，并具有四极杆的相互作用和离子之间的竞争交换力。我们的对称性启发分析反映了dzyaloshinskii-曼科潜在抗磁性有序的理论和3 k共线结构。奇异状态的实验测试包括中子和X射线布拉格衍射。
Cubic double perovskites that host heavy ions with total angular momentum J = 2 can exhibit a singular magnetic state epitomized by a lone octupole and bulk ferro-type magnetism. It exists in the Chen - Balents Hamiltonian with a quadrupole interaction and competing exchange forces between the ions. Our symmetry inspired analysis mirrors the Dzyaloshinskii - Man'ko theory of latent antiferromagnetic ordering, and a 3-k collinear structure. Experimental tests of the singular state include neutron and x-ray Bragg diffraction.
