Ni(x):YIG (x=% 1, 3 ve 5 ) İnce Filmlerin Yapısal ve Manyetik Özelliklerinin İncelenmesi

Abstract

In this study, Y3Fe5O12 shortly named YIG thin film and various concentration of Ni doped YIG thin films have been grown on quartz substrate using vacuum free spin-coating methods. Structural and magnetic properties of YIG and Ni(x):YIG (x=1, 3 and 5%) thin films grown on quartz substrates were investigated by performing X-ray diffraction and vibrating sample magnetometer experiments, respectively. Figure A. Schematic representation of YIG and Ni(1, 3 and 5 %):YIG thin films on quartz substratePurpose: In this study, the following items are intended: Using quartz substrates instead of highly cost GGG (Gallium-Gadolinium-Garnet) substrates and minimizing production costs, lowcost YIG thin film production by using vacuum-free spin coating system and low Ni contribution to improve magnetic properties of YIG thin films.Theory and Methods: YIG and Ni:YIG were grown on quartz substrates by vacuum-free spin coating in various recipes. The structural and magnetic properties of these thin films were characterized by X-Ray Diffraction and Vibrating Sample Magnetometer.Results: In this study, YIG and Ni doped YIG coated quartz substrates are discussed in various aspects. Crystallographic results show that YIG crystallizes in a single phase cubic garnet structure and also Ni patterns are observed in various Ni samples. In addition, nickel addition of ferrimagnetic YIG deteriorated magnetic anisotropy. Conclusion:YIG and Ni:YIG samples were produced successfully by using vacuum-free spin coating method. In addition, the targets (sub-cost, production cost) were successfully realized. Structural features are successful for YIG. However, with the addition of nickel, the structure was thoroughly disrupted. In addition, due to the ferrimagnetic nature of Ni, disrupting YIG's magnetic anisotropy while it is expected to increase the magnetic properties of YIG.
