2Reversible control of magnetic and transport properties of NdNiO_(3-δ)epitaxial films显示文摘Rare-earth nickelates possess intrinsic charge order,orbital order,and electron-lattice coupling,which make them very interesting for applications in oxide-based electronic devices.In this study,we grew NdNiO_(3-δ)(NNO) films with oxygen pressures changing from 27 to 10^(-5) Pa.With decreasing oxygen pressure,the antiferromagnetic state of the NNO film becomes a ferromagnetic state,and the resistance increases significantly.According to combined X-ray absorption spectro scopy and X-ray linear dichroism measurements,the ratio of Ni^(2+)-ions increases with decreasing oxygen-pressure,and the preferred orbital occupation changes from x^(2)-y^(2) to 3 z^(2)-r^(2).In addition,using the ionic-liquid gating method to control the migration of oxygen vacancies,both the magnetic properties and resistance of NNO films can be modulated reversibly.The oxygen vacancy induces a valence in the Ni ions and the orbital occupation changes,which alters the magnetic properties and the electronic transport in these NNO films.This study describes a novel tunable method for electronic devices that use NdNiO_(3-δ) films,and opens new doors for future improvements and functionalities.Huihui Ji Guowei Zhou Jun Zhang Xiaojiao Wang Xiaohong Xu 2021Journal of Rare Earths2021,39,3:0
