“…There are several methods to prepare the magnetic garnet films by using spin-coating methods. The metal-organic decomposition method [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ] and the sol-gel method [ 24 , 25 , 26 , 27 , 28 , 29 , 30 ] are generally used, but heat treatment at the temperature from 600 to 900 °C. is necessary as with the sputtering method.…”

Non-destructive testing using a magneto-optical effect is a high-resolution non-destructive inspection technique for a metallic structure. It is able to provide high-spatial resolution images of defects. Previously, it has been difficult to fabricate flexible magneto-optical sensors because thermal treatment is necessary to crystallize the magnetic garnet. Therefore, it was not possible to apply magneto-optical imaging to complicated shapes in a test subject, such as a curved surface. In this study, we developed a new process for deposition of the magnetic garnet on the flexible substrate by applying the magnetic garnet powders that have already undergone crystallization. In this new process, as it does not require thermal treatment after deposition, flexible substrates with low heat resistance can be used. In this paper, we report our observations of the optical properties, magnetic hysteresis loop, crystallizability and density of the particles on the flexible substrate deposited by the spin-coating method.
