摘要：
Thick films of YIG (yttrium iron garnet), which is well-known as magnetic material for microwave devices, were prepared on YSZ (yttrium stabilized zirconia) substrate by screen printing process. Y2.9Ca0.1Fe4.9Zr0.1O12 (Y3-xCaxFe5-xZrxO12 where x = 0.1) thick film exhibited good magnetic. properties of saturation magnetization 4piM(S) = 1550 G and ferromagnetic resonance linewidth DeltaH = 116 Oe. In order to enhance these magnetic properties of YIG thick films, pressure was applied to each thick film in a CIP (cold isostatic pressing) equipment. It has been concluded that CIP plays a role reducing the porosity of the thick films. We derived the relationship between DeltaH value and porosity. Due to the effect of CIP on YIG thick films, 4piM(S) increased up to 1680 G and DeltaH decreased to about 79 Oe with applied pressure.
