Description
Co$_{0.05}$LaTi$_{0.95}$O$_3$ nanofibers with average diameter of 201 – 264 nm have been successfully fabricated by electrospinning method. The crystal structure of nanofibers calcined at 400 – 700 $^o$C shows amorphous structure. The Co$_{0.05}$LaTi$_{0.95}$O$_3$ nanofibers calcined at 800 oC had cubic perovskite-type structure with secondary phase. The average crystallite sizes of nanofibers calculated from Scherrer’s formula were found to be 8.6 nm. The nanofibers of Co$_{0.05}$LaTi$_{0.95}$O$_3$ calcined at 400 – 600 $^o$C exhibit diamagnetic properties. The sample of nanofibers calcined at 700 and 800 $^o$C revealed room-temperature ferromagnetism behavior with the highest magnetization of 2.6 emu/g observed in the sample calcined at 800 $^o$C. It was found that the magnetization value increased with increasing calcination temperature.
