▎ 摘　　要

NOVELTY - The structure (100) has a conductor film (14) that is provided on a support substrate (12). An insulation magnetic film (16) is provided on the conductor film, and a conductor wire (18) is provided on the insulation magnetic film. The insulating magnetic film is made of a magnetic garnet and yttrium iron garnet. The conductor film and conductor wire are made of copper, aluminum, gold, silver, platinum, iron, a transparent conductor, a superconductor, a graphene, and conductive material and contains conductive magnetic substance. The thickness of the insulating magnetic film is 10 m or less. The conductor wire is provided with thickness of 1 m or less and a width of 5 m or less. USE - Spin wave excitation detecting structure such as transducer or antenna for exciting and detecting spin wave. ADVANTAGE - The spin wave excitation detecting structure achieves high strength of structure, high spin wave strength capable of being excited, and wide frequency band spin wave which is excited. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the spin wave excitation detecting structure. 12Support substrate 14Conductor film 16Insulation magnetic film 18Conductor wire 100Spin wave excitation detecting structure
