Abstract
We report on magneto-electric (ME) effects in core-shell nanofibers of hexagonal ferrites and ferroelectrics synthesized by electrospinning. The core-shell structure in annealed fibers of M, Y, and W-type hexagonal ferrites and PZT was confirmed by electron and scanning microwave microscopy. Fibers showed ferroelectric polarization and magnetization smaller than for bulk samples. The ME coupling strength was measured by magnetic field H induced polarization and ME voltage coefficient (MEVC). In SrM-PZT fibers the remnant polarization decreased by as much as 20% with the application of H. The highest MEVC was measured for magnetic field assembled films of SrM–PZT fibers.
