Nickel-doped lanthanum calcium manganese oxide polycrystalline ceramic target material
The invention discloses a nickel-doped lanthanum calcium manganese oxide polycrystalline ceramic target material, and belongs to the technical field of electronic ceramics. The chemical formula of the nickel-doped lanthanum calcium manganese oxide polycrystalline ceramic target material prepared by adopting sol-gel is La < 0.67 > Ca < 0.33 > Mn < 1-x > Ni < x > O < 3 >, wherein x is more than 0 and less than 0.05. According to the invention, Ni is doped in the Mn site of the La < 0.67 > Ca < 0.33 > Mn < 1-x > Ni < x > O < 3 > polycrystalline ceramic target material, so that on one hand, the resistivity is increased by utilizing the influence of Mn site doping on the material resistance, and the transition temperature of a metal insulator is shifted to a low-temperature region; on the other hand, the disorder of the system can be improved by increasing the doping amount of Ni, ferromagnetic clusters are separated, and the antiferromagnetism of the system is improved.
本发明公开一种镍掺杂镧钙锰氧多晶陶瓷靶材，属于电子陶瓷技术领域。本发明采用溶胶凝胶制备的镍掺杂镧钙锰氧多晶陶瓷靶材的化学式为La0.67Ca0.33Mn1‑xNixO3，其中0＜x＜0.05。本发明Ni掺杂在La0.67Ca0.33Mn1‑xNixO3多晶陶瓷靶材的Mn位中，一方面利用Mn位掺杂对材料电阻的影响，增大电阻率，使金属绝缘体转变温度向低温区偏移。另一方面，增加Ni的掺杂量能够增大体系的无序性，铁磁团簇被分离，增加了体系的反铁磁性。
