Abstract:
In this study, quaternary iron oxide compounds with Zn, Ni, Co metal dopants were grown by using Spray Pyrolysis (SP) technique. The structural, optical, electrical and magnetic properties of NixZn1-xFe2O4 (0<_x<0.7) and CoxZn1-xFe2O4 (0<_x<1) compounds have been carefully studied. XRD, XPS, Raman and FE-SEM techniques have been used for structural and morphological analysis; Absorption technique has been used for band gab calculate; Hall and Vibrating sample magnetometer (VSM) techniques have been used for electrical (resistivity, Hall mobility, carrier density) and magnetic properties. XRD analysis of the growth films revealed that, NixZn1-xFe2O4 and CoxZn1-xFe2O4 films have cubic polycrystalline structures. The XPS results show chemical environmental properties. Raman analysis result showed that, characteristic Raman shift peaks belonging to Fe2O3 (217 cm-1 , 275 cm-1 ), ZnxFe3-xO4 (382 cm-1 , 483 cm-1 ), NixZn1-xFe2O4 (462 cm-1 , 677 cm-1 ) and Co2ZnO4 (459 cm-1 ,612 cm-1 ) compounds were in the strenching mode. SEM-EDAX analysis showed that, the crystal structure and grain boundaries of the structure have been seen and the crystal structure has been formed. In terms of optical properties, the band gap values are 2,00 eV, 2.10 eV respectively. According to Hall measurements used to characterise electrical and magnetic properties, the p-type carrier density values of NixZn1-xFe2O4 and CoxZn1-xFe2O4 films were 1,064*1016 cm-3 , 3,80*1015 cm-3 respectively. Finally, the resulting from the VSM measurement according to the intensity hysteresis curves, we can write NixZn1- xFe2O4 relatively is hard magnetism, CoxZn1-xFe2O4 relatively is soft magnetism. When evaluating films grown by SP technique in terms of device applications; CoxZn1-xFe2O4 and NixZn1-xFe2O4 films are suitable for magnetic rectifier contact of spintronic applications.
