Magnetic Properties of Zn_1-xMn_xO and Zn_1-2xMn_xLi_xO Nano Materials

Zn_1-xMn_xO nanorods and Zn_1-2xMn_xLi_xO nano-particles were synthesized by solvothermal method at 160 oC. X-ray diffraction and Raman results showed that Mn ions were well incorporated into the ZnO matrix. No magnetic hysteresis were found in the magnetization curves. The hyperfine structures were observed in electron spin resonance spectra, indicating no ferromagnetic interaction between substituted Mn ions. The co-doping of Li can only change the morphology not the magnetic properties.
