Fig. 4 a Dependences of dielectric permittivity on frequency from 100 Hz to 10 MHz of BaTiO3 nanofibers and particles after annealing at different temperatures. b Dielectric permittivities calculated by the MG equation for BaTiO3 nanofibers and particles after annealing at different temperatures at 1 kHz. The variation of dielectric loss with annealing temperatures is also superimposed.
