“…The samples present agglomerates morphology and elongated particles, characteristics of materials with garnet structure. The particles clusters formation is associated of long-range magnetic dipole-dipole particles interaction [13,14]. It can be noticed that, with the increase in temperature, there is an increase in the size of the particles, which agrees with the results obtained by XRD for the crystallite sizes.…”

Herein, we present a study about the calcination temperature effect on the structural and magnetic properties of the Y3Fe5-xLaxO12 compound. The refinement of the X-ray diffraction patterns confirmed the YIG single phase formation for sample calcined at 900°C, while for the samples sintered at 1000°C and 1100°C, it was verified the phase segregation belonging to the YFeO3 compound. The average crystalline size increases with the temperature, which may be related to the nucleation and growth mechanisms that are favored by temperature. The samples have an agglomerated morphology and an irregular elongated shape. The magnetic properties show variation in the magnetic moment of the compound as the phase formation temperature increases. At temperatures of 1000°C and 1100°C, the effects of the secondary phase are added to the magnetism of the compound, causing variations in the saturation magnetization and in the effective anisotropy field.

“…To further increase the concentration of oxide particles to improve the material properties, it is necessary to add other rare earth elements. Er not only forms oxide particles but can also form magnetic intermetallic compounds with transition metals, which can play a magnetic refrigeration role and prevent the reactor from overheating and causing accidents [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Therefore, ODS steel containing the Fe–Cr–Er system is a potential nuclear reactor cladding material.…”

Phase relations of the Fe–Cr–Er system in the temperature range 973–1273 K were experimentally investigated using equilibrated alloys. The isothermal sections consisted of 9 single-phase regions, 16 two-phase regions, and 8 three-phase regions at 973 K and 1073 K. At 1273 K, the σ phase disappeared, and liquid appeared. All single phases had a solid solubility range that showed a downward trend with a decrease in temperature. The homogeneity range of the ErFe12−xCrx ternary compound was determined to be x = 1.8–4.5. The more accurate phase relations obtained in this work can better guide the preparation of Fe–Cr–Er alloys in actual production.

“…[8,9] To achieve the desired properties, the preparation conditions and the appropriate substitution to the pure YIG is must. [10][11][12] Recently, Ramesh et al reported that the temperature stability of YIG material is low and that it can be operated in low power microwave devices. [13] In this view, there are several researchers who study the properties of YIG with different ion substitution.…”

In this study, the structural and magnetodielectric properties of gadolinium (Gd 3+ ) substituted yttrium iron garnet (Y 2 GdFe 5 O 12 ) are investigated. The hydrothermal synthesis method is used to prepare the powders. The prepared powders are sintered at three different temperatures. X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) are used to characterize the structural and morphological properties of the sintered samples. The dielectric properties are measured over a frequency range of 100 Hz-1 MHz. A vibration sample magnetometer (VSM) is used to determine the magnetic parameters of the samples and it is observed that the magnetic properties of the samples depend on the sintering temperature. The thermal change in magnetization parameter and the transition temperature of the samples are measured using the pulse magnetometer by applying 5kOe magnetic field. The collected results are analyzed and discussed using various theories.
