A system and a method for reducing critical current of magnetic random access memory (MRAM) are disclosed. The magnetic device includes at least a pinned layer, a spacer layer and a free layer, and the material of the pinned layer and the free layer is perpendicularly anisotropic ferrimagnetic. The spacer layer is an insulator. By the modified Landau-Lifshitz-Gilbert equations, the varying trend of the critical current can be estimated.
