摘　　要：近年来,多铁性材料KBiFe2O5 (以下简称KBFO)由于其窄带隙等性质而受到广泛的关注,该材料在光催化以及铁电光伏领域具有良好的应用前景。为进一步优化该材料的物理性质,本文采用溶胶凝胶法(Sol-Gel)合成出一系列不同掺杂浓度的Ni2+掺杂KBFO样品,旨在研究Ni2+掺杂对于KBFO块体样品磁学性质的影响。结果表明:掺杂浓度的提高使得KBFO的磁学性质有所提升。In recent years, the multiferroic material KBiFe2O5 (hereinafter referred to as KBFO) has received extensive attention due to its narrow band gap and other properties. This material has good application prospects in the fields of photocatalysis and ferroelectric photovoltaics. In order to further optimize the physical properties of the material, a series of Ni2+ doped KBFO samples with different doping concentrations were synthesized by sol-gel method (Sol-Gel), aiming to study the effect of Ni2+ doping on the magnetic properties of KBFO bulk samples. The results show that the magnetic properties of KBFO are improved with the increase of doping concentration.
