Popis:	Polyvinylpyrrolidone-based nanocomposite fibers containing (Ni0.6Zn0.4)Fe2O4have been successfully fabricated by an electrospinning technique. Magnetic measurements were made, individually, on polyvinylpyrrolidone, the ferrite nanoparticles, and several fibrous nanocomposites. The polymer exhibits a diamagnetic susceptibility comparable to the estimated value from Pascal’s constants. The nanocomposites maintain intrinsic properties of pure (Ni0.6Zn0.4)Fe2O4, with a weighted magnitude according to its concentration in a given fiber. Meanwhile, superparamagnetism prevails with a relatively low blocking temperature, assuring no aggregation of the fine particles. Such electrospun materials are flexible and have large surface area per unit mass, thus suitable for certain applications in environmental and biomedical engineering.
