| Abstract: | This paper investigates the integrable inhomogeneous generalized Heisenberg ferromagnet model by using the prolongation structure theory. By associating the spin vector of the inhomogeneous generalized Heisenberg ferromagnet with the binormal to a moving curve in Minkowski space, the corresponding equivalent coupled inhomogeneous integrable equation is present. |

| Keywords: | inhomogeneous Heisenberg ferromagnet space curve integrable equation |
