چکیده انگلیسی
There is an urgent technical requirement of lowering the sintering temperature of Y3Fe5O12 (YIG) for its practical applications. In this paper, a modified solid state reaction method is reported by adding the surfactant of cetyltrimethylammonium bromide (CTAB). A high sintering temperature of 1200 °C is required for the formation of YIG phase without adding CTAB, which is effectively decreased to 1050 °C by adding CTAB. The morphology studies show that the sintering temperature plays the main role in the crystal growth and excludes the possible contribution of CTAB. The prepared YIG ceramic samples show soft ferromagnetic properties, with coercivity of only 21.2 Oe for the sample prepared with CTAB at 1050 °C, which decreases with increasing sintering temperature. The main role of adding CTAB is preventing the agglomeration of ball milled ultrafine source particles, which may facilitate the interdiffusion among them and promote the reaction at lower temperatures. Furthermore, the Gilbert damping constant is significantly reduced for YIG prepared by adding CTAB, which is one order smaller than that without CTAB.
