The invention relates to a high magnetostriction coefficient Fe-Ga-based thin strip and a preparation method thereof. The invention adopts die casting, slab continuous casting, thin slab continuous casting and thin strip continuous casting slabs, and can carry out large-scale production simply and efficiently by using traditional rolling and annealing processes; establishes low-temperature inherent inhibitor + nitriding inhibition Agent system, control heat treatment and rolling process to precipitate fine Cu 2 S, Nb(C,N) and V(C,N) or their composite precipitates are used as the main intrinsic inhibitors. When the intrinsic inhibitory force is insufficient, nitriding is used to supplement the formation of nitrides such as AIN or BN before secondary recrystallization annealing. , to achieve flexible control of the suppression force; finely adjust the cold rolling parameters to ensure that the primary recrystallization obtains a fine and uniform structure and a favorable texture, and realize the coordination and matching of the structure, texture and inhibitor before the secondary recrystallization, and obtain a perfect and sharp Secondary recrystallization of Goss ({110}<001>) texture. The magnetostriction coefficient (3 / 2)λs of the finished Fe-Ga-based thin strip of the present invention is as high as 220-370ppm.
