In this study, amorphous FeGaSiB thin films have been fabricated on silicon (100) substrates using a co-sputtering-evaporation deposition system. By fixing the sputtering parameters (chamber pressure and power of the FeSiB target), and only varying the Ga evaporation rate, how the morphology, magnetic properties, and magnetostriction constants changed with the addition of Ga were investigated. This was to increase the Ga concentration, while maintaining the optimized fabrication parameters established in previous work. It was determined that the percentage of Ga increased linearly as the Ga evaporation rate was increased. The x-ray diffraction (XRD) results indicated that all the films were amorphous and the only detected peaks were for the Si substrate. The results showed that varying Ga evaporation rate, thus Ga content, affected the magnetic properties of the films by reducing the saturation induction along with increasing the uniaxial anisotropy within the films. The magnetostriction constants measured were in the range of 10.2 ppm to 17.2 ppm.

The control of magnetism by acoustically induced strain has driven significant research activities, with the ultimate goal of pursuing novel, ultrafast, compact, and energy-efficient electronic and spintronic applications. Here, we aim to present for the first time a comprehensive review of this field, which has seen a surge of interest in recent years. We review fundamental understanding of magnetoelastic coupling phenomena and mechanisms, diverse experimental configurations, recent advances in modeling and microscopic tools to intuitively describe them, and the experimental and theoretical exploration of devices and technological innovations. These include acoustic spintronics, surface acoustic wave (SAW)-assisted spin transfer torque (STT) switching, SAW-assisted all-optical switching (AOS), SAW-driven spin textures (e.g., Skyrmions and domain walls), acoustic Terahertz emitters, SAW magnetic field sensors, magnetoelastic antenna, on-demand magnonic crystals, and so on. Focusing on the translation of many fundamental research breakthroughs into potential technological applications, we identify the key challenges and opportunities in the field, which we hope may motivate further research efforts of moving scientific discoveries toward real applications.
