Abstract The ultralong and aligned YMnO3/PVP composite nanofibers have been synthesized by sol-gel based on modified electrospinning setup. After calcining the as-spun YMnO3/PVP fiber at 900oC for 6 h in air atmosphere, the single-crystalline hexagonal YMnO3 (H–YMnO3) nanofiber can be obtained. The fabricated products were characterized by SEM, XRD, TEM, SAED and VSM to reveal the phase purity, morphologic, crystalline structure and magnetic properties. The results show that the YMnO3/PVP composite nanofibers presented smooth surface, high alignment degree and a rather uniform diameter around 150–230 nm over a length of several meters, the H–YMnO3 nanofibers exhibited lotusroot-like morphology and surface-smooth; and have a reduced diameter ranging from 70 to 100 nm. H–YMnO3 nanofibers has weak ferromagnetism at room temperature.
