Enhancement of ferromagnetic and dielectric properties in lanthanum doped BiFeO3 by hydrothermal synthesis
TL;DR: In this article, it was found that the morphologies of as-obtained micron-sized particles turned from spheroidal to octahedral according to different doping levels, and the dielectric constant of Bi 1- x 1 La x FeO 3 sample increased after La doping, and reached the largest value for the sample of x = 0.2, both in low and high frequency range at room temperature.
