The emerging Ni-based superconducting oxide thin films are rather intriguing to the entire condensed matter physics.Here......

Applying a three-band model and the random phase approximation,we theoretically study the spin excitations in nickelate ......

研究了ＴｉＯ＿２掺杂ＬａＮｉＯ＿３的气敏特性，实验表明，在中等掺杂时，材料的电导适中，气敏性能最好；ＸＲＤ证实，掺杂后ＬａＮｉＯ＿３仍属于ＡＢＯ＿３钙钛矿结构，且有新相生成。还对掺杂ＳｎＯ＿２，Ｓｂ＿２Ｏ＿３及Ｖ＿２Ｏ＿５进行......

The chemical and electrochemical stability of lanthanide nickelates La2 NiO4+δ(LNO),Pr2 NiO4+δ(PNO)and their mixed com......
