Electrospun NiZn ferrite nanofibers have great potential due to their one-dimensional\nstructure and electrical properties, but they have a low reproducibility resulting from many process\nconfounders, so much research effort is needed to achieve optimized process control. For structure\ncontrol, the viscosity of the precursor solution is a likely parameter. One solution is to use polyvinyl\npyrrolidone (PVP) and metal nitrate to obtain the desired viscosity by increasing the nitrate content,\neven if the polymer content is decreased.............
