“…Owing to their high melting point, high resistivity at room temperature ________ (10 12 Ωcm), low electromagnetic loss, and high thermal stability, YIGs are often used in applications at high frequencies [1]. Recently, YIG has been the subject of sensing applications [2][3][4][5][6][7][8], especially those in the form of granules and thin films. Since the 1980 s, D'Amico et al, [9][10][11] have shown that the presence of covalently unbalanced doped ions such as Ca 2+ , V 5+ , Sn 4+ , Zn 2+ , etc.…”

Y3Fe5-xZnxO12 with x = 0; 0.02; 0.04; 0.06; 0.08; 0.1 (YIG) particle materials were fabricated by sol-gel method combined with heat treatment at 900 °C and 1,000 °C with different annealing times (2 h and 5 h) and heating rates (5 °C/min and 2 °C/min). X-ray diffraction patterns show that the obtained samples are single crystalline phases at the condition of an annealing temperature of 900 °C for 5 h and a heating rate of 2 degrees/min. FESEM images of the samples show particle sizes from the submicron to the micrometer. The magnetization of the samples decreases as the doping concentration increases. I-V characteristics and complex impedance spectra at room temperature of samples were measured. The results show that the resistivity value of the doped samples decreases in the range of 5-6 orders in magnitude compared with that of the pure YIG sample. The contribution of the grain boundaries to the impedance was analyzed. The conducting process is explained due to the tunneling of charge carriers across the grain boundary.

“…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.…”

Properties of Magnetic Garnet Films for Flexible Magneto-Optical Indicators Fabricated by Spin-Coating Method

et al. 2022

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.

“…Substantial efforts are devoted to the studies of garnet/heavy metal bilayers, where the magnetism of garnet insulators is interacting with the electron transport in conductors with strong spin orbit interactions [8][9][10][11][12][13][14]. While many studies use perpendicular magnetized films [15][16][17][18][19][20][21][22][23], recent experiments also investigated the consequences of magnetization rotations at orientation transitions [24] and magnetization vanishing at the garnet's magnetic compensation temperature [9,21].…”

Thin garnet films with perpendicular anisotropy are enjoying renewed attention in the context of research on heavy metal/ferromagnetic insulator bilayer devices with tunable electric and magnetic properties. We show that two temperature-induced magnetic orientation transitions observed in such films have different origins. One transition occurs between the uniform, in-plane magnetized state and the stripe domain state, and is governed by the bulk material properties. The other occurs between the domain state and the perpendicular magnetized uniform state, and is governed by the physics of domain nucleation.
