A 200-MHz acoustic-surface-wave isolator has been constructed employing an epitaxial layer of Ga-doped YIG on a gadolinium gallium garnet substrate.

Instrum. 85, 104707 (2014); 10.1063/1.4898179 Strong asymmetrical doping properties of spinel CoAl2O4Measurements are reported of the attenuation of microwave phonons of various modes in magnesium aluminate spinel (MgAbO,). The attenuation of certain modes is lower than in any other material measured and permits the observation of 9000 MHz echo patterns at room temperature. Some possible applications of this discovery are discussed. The attenuation at room temperature is interpreted in terms of an effective viscosity damping mechanism and approximate values of the components of the viscosity matrix are given.
