| Description |
The enhancement in ferromagnetism and ferroelectricity at room temperature for Pb0.7Sr0.3�Fe0.012Ti0.988�O3 �PSFT� nanoparticles is proved by magnetization and polarization
hysteresis loop. The x-ray diffraction and micrograph show that the PSFT nanoparticles have distorted tetragonal single phase, and their average particle’s size is 8 nm. The effect of Sr content reduces the particle size, and hence the multiferroic system becomes more resistive, which
dominates the superparamagnetic/paraelectric relaxation. The variable-range-hopping conduction mechanism explained the high resistivity of PSFT nanoparticles, which suggests that the room temperature movement of electrons involves short-range order through defect states.
