Abstract
A study was made to evaluate the impacts of stoichiometry and sintering temperature on hysteresis properties of an Mn, Al substituted Y3Fe5O12 (YIG) ferrite. The Mn, Al substituted YIG ferrite, (Y3)(MnxAl0.83-xFe4.17)O12 showed the best properties for application in 2-4 GHz frequency range (i.e., S-band) latching phase shifter at x =0.13 . Magnetic characteristics were further improved by sintering process. The increasing sintering temperature increases saturation magnetization (4π Ms), remanence (Br), and squareness ratio, while decreasing the coercivity (Hc). In addition, good ferromagnetic resonance linewidth (i.e., ΔH) properties were also realized as 38.6 Oe at 3.2 GHz. Based on above magnetic characteristics, (Y3)(MnxAl0.83-xFe4.17)O12 is a good candidate for practical latch phase shifter applications at S-band.
