Abstract

The invention relates to the field of ceramic target materials, and particularly relates to a nickel-based target material and a preparation method and application thereof. The Nd<1-x>AxNiO3 ceramic target material which is pure in component, uniform in element and density distribution and good in mechanical strength, hardness and density is prepared through a production process of ball-milling, presintering, secondary ball-milling, granulation, blank making, rubber discharging, programmed temperature rising and sintering and programmed cooling, a Nd<1-x>AxNiO3 film can be obtained through magnetron sputtering growth of the Nd<1-x>AxNiO3 ceramic target material, and the film has good crystallinity and high-quality single crystal epitaxy property. In addition, the invention further providesthe Nd<1-x>AxNiO2 film, and the Nd<1-x>AxNiO2 film has excellent superconducting characteristics and electrical transport properties.

Description

technical field [0001] The invention relates to the field of ceramic targets, in particular to a nickel-based target and its preparation method and application. Background technique [0002] Superconducting materials refer to materials with zero resistance and the property of repelling magnetic field lines below a certain temperature. Superconducting materials are widely used in precision detection components, energy storage, computers, etc. Since the discovery of superconducting materials more than 100 years ago, superconducting materials such as copper-based and iron-based materials have been discovered one after another. However, it was not until 2019 that nickel-based superconductivity was realized. [0003] Nd 1-x A x NiO 3 (A=Ca or Sr or Ba) Nd obtained after reduction 1-x A x NiO 2 It can be used for the preparation of nickel-based superconducting thin films. In addition, it also has the electrical transport properties of metal-insulator phase transition. Howev...
