Abstract:	• Electrospun nanofibrous mats of GdFeO 3 doped PbTiO 3 i.e. Pb 0.8 Gd 0.2 Ti 0.8 Fe 0.2 O 3 synthesized using the sol gel method. • Existence of a pure tetragonal phase, and the Scherer equation was applied to determine the average nanocrystallite size. • An in-depth morphological study is carried out to detect the effect of various factors such as applied voltage, needle-collector distance and flow rate on the nanofibrous mats. • Magneto-electric properties of the sample have been investigated. This study intends to create and analyze electrospun nanofibrous mats of GdFeO 3 doped PbTiO 3 i.e Pb 0.8 Gd 0.2 Ti 0.8 Fe 0.2 O 3 (GF-PT) using sol gel method. The polyvinylpyrrolidone PVP/GF-PT material was attempted to generate a highly viscous sol that is used to transform into nanofibers utilizing various parameters. The crystallographic parameters were estimated using X-ray diffraction (XRD) patterns, which supported single phase tetragonal structure. Also, Scherer equation was used to calculate the typical nanocrystallite size of the manufactured nanofibrous mats, and the result was 15.92 nm. The morphological investigations showed that a variety of factors, such as applied voltage, flow rate, and needle-collector distance, had a significant impact on the average diameter of nanofibrous mats. The nanofibers displayed ferromagnetic behavior and exhibited residual magnetism of approximately 0.0257 emu/g. The created nanofibers exhibit significant magneto-electric (ME) coupling characteristics having the highest magneto-dielectric response (MDR) at 1.2 T of about −38.62 % and the calculated magneto- dielectric coefficient value is −275.05 emu2/g2.
