Micrograph and crystal structure of high magnetostrictive susceptibility of Fe-Pd thin films

The magnetostriction induced shape memory effect (MSME) was investigated in the Fe-Pd thin films prepared by magnetron sputtering. The reversible relationship was obtained between shape change and applied magnetic field from earth magnetic field to 0.2 kOe. The high magnetostrictive susceptibility were detected at low magnetic field below 0.2 kOe at room temperature. These were higher than that of Tb _{0.3} Dy _{0.7} Fe _2 thin film developed.
