PROBLEM TO BE SOLVED: To provided a static magnetic wave device whose insertion loss is small, whose ripple is also small and which exhibits excellent characteristics. SOLUTION: A static magnetic wave device is a single crystal film 2 expressed by a general formula Y3-x Mx Fe5-y Ny O12 (M is at least one of La, Bi, Lu and Gd. N is at least one of Ga, Al, In and Sc. 0<x<=1.0, 0<y<=1.5). and which is formed on a Gd3 Ga5 O12 single crystal substrate 1 by liquid phase epitaxial method. The lattice constant of the single crystal film 2 is larger than that of the single crystal substrate 1 and the differenceΔa between these constants is within the range: 0.0004nm<=Δa<=0.001nm.
