摘要
对反尖晶石结构的LiNiVO4的磁学性质的研究表明:高温顺磁区研究表明材料存在自旋-轨道耦合作用;在低温区,由于其Li+/Ni2+无序占据八面体间隙位置,从而导致该材料几何失措效应的抑制;相应地体系呈现短程反铁磁有序态,Neel温度为35K.
The magnetic properties of inverse-spinel LiNiVO_4 have been investigated.It is found that there is a strong spin-orbit coupling effect in the system via fitting the paramagnetic data at high-temperature portion.A short-range antiferromagnetic ordering shows at low temperature with Neel temperature 35 K,which results from the restriction of the geometrical frustration due to the random distribution of Li＋/Ni 2＋ ions.
