文摘
- •
Electrospun La0.5Sr0.5TiO3 nanofibers with 148–208 nm in diameter have been fabricated.
- •
The prepared samples were well characterized by XRD, TEM, XPS, and VSM.
- •
The samples exhibit ferromagnetism, having the MS of 0.022–0.067 emu/g at 10 kOe.
- •
Oxygen vacancies play an important role on the RT-FM of La0.5Sr0.5TiO3 nanofibers.
- •
This work demonstrates a simple method can be used to fabricate the La0.5Sr0.5TiO3 nanofibers.
