This article reports the structure, microstructure, and magnetic properties of Sm-Fe films grown on Si <100> by DC magnetron sputtering. Films were grown with varying argon gas pressures, namely 5, 10 and 15 m.Torr, and keeping the sputtering power constant at 100 W. All the films were found to be amorphous in nature irrespective of the processing conditions. Microscopic investigation of film surface showed an island kind of surface morphology in the form of globules, whose sizes increased with increase in argon gas pressure. Thermomagnetic measurements indicated ferromagnetic behavior at room temperature for the film deposited with 10 and 15 m.Torr gas pressures. Magnetic measurements showed low anisotropy coupled with low coercivity for the films grown at higher gas pressures. A maximum magnetostriction of about 390 micro-strains has been achieved for an applied magnetic field of about 6 kOe. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
