Cu-and Ni-codoped FeZnO particles with the wurzite structure were successfully synthesized at low temperature by a co-precipitation method. The samples were characterized using a vibrating sample magnetometer, X-ray diffraction, energy dispersive X-ray spectroscopy, UV-Vis spectrophotometry and electron spin resonance. The results demonstrated that room temperature ferromagnetic order was observed in both samples and the magnetization was higher than that of Fe-doped ZnO. The correlation between the structural and magnetic properties is discussed. Figure 4. The room temperature ferromagnetic of Zn 0.96 Fe 0.01 Cu 0.03 O and Zn 0.96 Fe 0.01 Ni 0.03 O compared with Zn 0.95 Fe 0.05 O, n 0.94 Cu 0.06 O, and Zn 0.95 Ni 0.05 O nanoparticles. Z

We have realized single phase crystalline BaSi2 thin films on quartz substrate by vacuum evaporation for solar cell applications. This structure is achieved by introducing (111)-oriented poly-Si fabricated by aluminum induced crystallization as a supply layer prior to BaSi2 deposition. Raman measurements showed five characteristic peaks corresponding to [Si4] 4anions vibrations in BaSi2 for all films deposited at 400 o C and above. X-ray diffraction analysis showed that randomly-oriented orthorhombic phase of BaSi2 is achieved with no trace of secondary phases. Also, the crystal quality is enhanced at higher substrate temperatures.
