The effect of SrTiO3 addition on the magnetic and microwave properties of yttrium iron garnet.

The effect of SrTiO₃ addition on the microstructure and magnetic properties of yttrium iron garnet prepared by a conventional ceramic method was investigated using scanning electron microscopy, X-ray diffractometry, vibrating sample magnetometry, and ferrimagnetic resonance experiments. A YIG specimen sintered at 1693 K with 0.2 mol% SrTiO₃ addition showed above 98% densification of theoretical density without changing in magnetic properties of YIG. A YIG specimen sintered at 1693 K with 0.2 mol% SrTiO₃ showed ferrimagnetic resonance linewidth ΔH of about 80 Oe. [ABSTRACT FROM AUTHOR]
