| Popis: | An impediment to the use of epitaxial YIG (yttrium iron garnet) in microwave devices has been the drift of the ferrimagnetic resonance field with temperature. This drift arises from the temperature sensitivity of the demagnetizing and anisotropy fields. By substituting Ga for some of the Fe and La for some of the Y in liquid phase epitaxial YIG, the demagnetizing and anisotropy field contributions to the drift were made self compensating. Temperature stability was thus achieved in perpendicular resonance. In parallel resonance there was a substantial reduction in drift. |
