With its short name YIG (Y3Fe5O12) is one of the materials that has been intensely studied in recent years due to its hopeful applications in microwave communication systems and magneto-optical devices. Today, the YIG thin films are expanded on the Galyum-Gadolinium-Garnet basement named GGG. However, the high cost of the GGG underground restricts the production of YIG films economically. The preliminary studies we have done have shown that it is possible to expand the YIG thin film on the quarters. In this study, the GGG substrate was used with a lower cost and expected performance quarter substrate. YIG thin films were enlarged by the spin-cover method on the quartic substrate. The surface homogenity of the YIG thin film-covered samples produced under appropriate production conditions has been secured. The YIG films expanded on the quarterly bottom were found to be crystallized in a single-phase cubic garnet structure. The film has also been expanded in a similar way. With the magnetic field applied between -5000 Oe and +5000 Oe, magnetization values were measured and hysteresis curves were obtained.
