In the present work, Co impurities were introduced to host NBTO materials through the sol-gel method. Results demonstrated the reduction in the optical band gap of pure and Co-doped NBTO, and that the observed room temperature ferromagnetism in Co-doped NBTO materials originates as an intrinsic phenomenon. |
