The doping concentration of Mn can reach up to 9 at% without precipitation or secondary phase, confirmed by electron spin resonance (ESR) and synchrotron X-ray diffraction (XRD). Room-temperature ferromagnetism is observed in the as-prepared nanoparticles. However, the room-temperature ferromagnetism disappears after post-annealing in either argon or air atmosphere, indicating the importance of post-treatment for nanostructured magnetic semiconductors. © 2014, Luo et al.; licensee Springer. | Source Title: | Nanoscale Research Letters | URI: | https://scholarbank.nus.edu.sg/handle/10635/183697 | ISSN: | 19317573 | DOI: | 10.1186/1556-276X-9-625 | Rights: | Attribution 4.0 International |
