We present an ab initio study the effect of surface strain on magnetic anisotropy of Co and Fe monatomic wires deposited on Au(111) and Pt(111) surfaces respectively.We obtained that for all considered systems both compressive and tensile surface strains makes strong effect on MA of deposited metal monatomic wires. Surface strain provokes the redistribution of d-states in wire atoms which leads to the changing of coupling between d-states and as a follow to the changing of matrix elements in perturbative formula for MA energy.
