Abstract

This study investigated the structural, morphological and magnetic properties effects of silver (Ag) nanoparticle doping at low doping rates on Y3Fe5O12 (YIG) thin films. In the first stage of the study, Ag nanoparticles were synthesized by polyol method. In the second stage, both undoped YIG and 0.25%, 0.50% and 1% doped YIG thin films were grown on thermally oxidized Si substrates using sol-gel method. All films were crystallized crack-free by a two-step heat treatment process. XRD patterns confirm the YIG crystal structure and the Ag crystal structure, which is embedded in the structure without bonding with the YIG components. SEM images revealed that the Ag NPs synthesized by the polyol method have a homogeneous distribution. The surface morphology of the thin films showed that Ag NPs doping formed small islands on the surface morphology. While the saturation magnetization (Ms) values of the samples were very close to each other regardless of the doping rate, the coercive field values (Hc) increased remarkably with Ag doping. This value tends to decrease as the doping ratio increases. 0.25% AgNPs sample has the highest Hc value. Ms values between in-plane and out-of-plane measurements of the films increased with Ag concentration. As a result of all analyses, it was observed that all crack-free thin films were successfully obtained by optimizing the production parameters of the sol-gel method, which is a relatively inexpensive and easy method. Silver nanoparticle doping was found to improve the structural and magnetic properties of YIG thin films. It is predicted that this improvement will contribute to other properties of YIG thin films used in magneto-optical applications.
