Summary: This study investigates the magnetoelastic behavior of Fe1-xGax thin films grown on glass and oxidized Si(100) amorphous substrates. It was found that the magnetoelastic response is larger for samples on glass compared to those on Si(100), and the response increases with higher concentrations of Ga for both substrates. Additionally, increasing substrate temperature during growth does not significantly affect the magnetoelastic behavior of samples on Si(100). The experimental behavior is well described by a model that considers elastic grain interaction for isotropic systems.

Summary: This paper demonstrates the potential use of electrodeposition to synthesize a hybrid magnetostrictive/magnetoelectric layered system by adjusting pH, growth potential, and electrolyte composition. X-ray diffractometry and electron microscopy observations reveal the formation and distribution of FeGa, GFO, and Fe oxides in the thin films. The magnetic behavior and segregation of Fe oxide in the samples are also analyzed and monitored.

Summary: We have fabricated high-quality polycrystalline Fe1-xRhx composition-spread thin films and investigated their structural and magnetic transformations. The Fe1-xRhx film undergoes a phase transition from α to γ phase, accompanied by a magnetic transition from ferromagnetic to paramagnetic phase, as the Rh concentration increases. We constructed a thin-film phase diagram of Fe1-xRhx based on the structural and magnetic properties, which showed slightly different transition behaviors compared to bulk alloys.

Summary: In this study, Fe-Ga films with macroporous structure were prepared by electrodeposition on metallized silicon substrates templated with sub-micrometer-sized polystyrene spheres, showing larger magnetic-field-induced crystal deformation compared to non-templated and fully-dense films. These effects in porous Fe-Ga films are promising for the design of various strain-engineered nanomaterials.

Summary: A holistic approach combining atomistic modeling and ab initio calculations is used to study the atomic order and finite-temperature magnetostrictive behavior in the binary alloy Galfenol. The study reveals the potential to enhance magnetostrictive properties by adjusting the electron content in the system.

Summary: This paper investigates the vicinities of two resonance points where longitudinal and transverse elastic waves interact with the magnetic mode. It calculates the caustic patterns of magnetoelastic waves (MEW) in Fe1-xGax galfenol crystals with two compositions (x = 0.18 and x = 0.086). The study of MEW focusing and caustic is based on the analysis of constant frequency surfaces obtained in the continuous medium model. The research reveals that the caustic patterns significantly depend on the magnitude of external magnetic field and galfenol composition.

Summary: This study presents a method for generating stable and spatiotemporally controllable gradients in a microfluidic environment using a reaction-free electrokinetic technique. The results suggest that ion concentration gradients can be established in a fluid by controlling the amplitudes and frequencies of the alternating current electric field. This research is important for both electrokinetic and biological applications.

Summary: Spherical Tb0.5Dy0.5(Fe1-xMnx)1.92 (x 1/4 0, 0.05, 0.10 and 0.15) single-crystal particles were prepared, and the study found that the magnetic anisotropy of the alloy decreases as x increases from 0 to 0.15. Subsequently, giant magnetostrictive composites with well <111>-oriented Tb0.5Dy0.5(Fe1-xMnx)1.92 particles were obtained, showing a better magnetostrictive property compared to commercially available Terfenol-D.

Summary: In this study, individual nanotube-based ME films of CoFe2O4/BaTiO3 were developed with optimized magnetostrictive phase, piezoelectric phase, and interface between the phases. These ME films demonstrated enhanced dipole moments and high ME coefficient, showing potential for applications in high-sensitive magnetic sensors or low-power energy harvesters.

Summary: This work designed an optimized magnet focusing structure to increase the sensitivity of the fiber optic current sensor based on magnetostrictive composite material. The influence of the magnetic focusing structure on the sensor's performance was analyzed and validated through theoretical modeling and simulation. Experimental tests showed that the proposed sensor was more sensitive than the traditional ones.

Summary: The structural, magnetic, and magnetostrictive properties of two-sublattice Tb0.27Dy0.73(Fe1-xAlx)2 polycrystalline intermetallic ferrimagnets (x = 0-0.2 and 1.0) were investigated. X-ray powder diffraction, magnetometry, and strain gauge magnetostriction measurements were performed. The material Tb0.27Dy0.73(Fe0.9Al0.1)2 showed promising piezomagnetic coefficients, even higher than Terfenol-D, indicating its potential use in magnetoelectric composites.

Summary: Through the synergy of multiple characterization techniques, a deep understanding of the structure-property relationships in Fe-Ga alloys before and after annealing has been achieved. It was found that the D03 phase is gradually replaced by the A2 phase during annealing, and the A2 phase is responsible for the characteristic magnetic structure and significant improvement in magnetostriction performance.
