Abstract
ABSTRACT The magnetic field-assisted approach had been applied in the synthesis of Mn-doped ZnO diluted magnetic semiconductor via the hydrothermal method. The effect of high static magnetic field (HSMF) on the structures, morphologies and magnetic properties of the samples were characterised. X-ray diffraction and X-ray photoelectron analysis revealed that Mn ions had been doped in the hexagonal wurtzite ZnO and there were no any other detectable phases observed. Energy dispersive spectroscopy revealed that the content ratio of Zn to Mn was about 19:1. In addition, transmission electron microscopy and high-resolution transmission electron microscopy studies confirmed that Zn0.95Mn0.05O was nanorods in shape, and the growth rate of the nanorod was obviously restrained. While more oxygen vacancies (V O) had been introduced with increasing the magnetic flux density. Finally, magnetisation measurements implied that all of the Zn0.95Mn0.05O samples were room-temperature ferromagnetism and their magnetism was improved by the HSMF.
