FIELD: manufacture of small-size planar SHF instruments. SUBSTANCE: epitaxial ferrite garnet structure containing substrate made of gadolinium-gallium garnet of orientation (100) comprises ferrite-yitrium garnet film containing Ga, La and/or Se and disorientated from plane (100) to plane (110) through angle of α. The proposed structure allows for thermal stability of excitation frequencies of surface magnetostatic waves within temperature range of from -70 to +85 C. EFFECT: improved properties of the title structure. 1 cl, 2 dwg
