Structural and magnetic properties of BiFeO3-PbTiO3 polycrystals. (3rd October 2018) - Freitas, V. F.
Abstract: In this manuscript, microstructural, structural and magnetic properties of pure and La doped (0.6)BiFeO3 -(0.4)PbTiO3 polycrystals were investigated. X-ray diffraction, transmission and scanning electron microscopy results reveal morphologically uniform particles of rhombohedral and rhombohedral/tetragonal symmetries for pure and La doped samples. An enhanced magnetization, characterized by slim loop hysteretic curves of null remnant magnetization and 2 emu/g saturation (15 kOe) magnetization, is observed at room temperature for samples with average particle size close to 5 nm.
