“…Interestingly, the more stable cubic structure can be recovered by thermal annealing. This B2 ordering has noticeable consequences on the magnetic properties [20][21][22]; in particular, the induced spatial anisotropy is responsible for the perpendicular magnetic anisotropy observed in this system [14].…”

Bulk Fe 1−x Ga x alloys present a strong sensitivity of the magnetostrictive properties with Ga content with maximum magnetostriction near x = 0.19. Here, we present magnetoelastic coefficients measured by the cantilever method on Fe 1−x Ga x thin films grown by molecular beam epitaxy on GaAs(001). We find that Ga-dependent magnetoelastic coefficients in nanometer thin films are comparable in magnitude to the respective bulk values. Moreover, we compare thin films with a tetragonal structure due to a slightly preferential alignment of Ga pairs along the growth direction with and a cubic structure. It turns out that magnetoelastic coefficients are unaffected by a preferential alignment of Ga pairs along the growth direction.

“…In Ref. [14], we show that the cubic structure is composed of tetragonal B2 grains with c axes (parallel to the Ga pairs) randomly oriented along the three spatial directions. On the other hand, the tetragonal structure occurs due to a spatial imbalance of the B2 grains, i.e., a larger fraction of Ga pairs along the growth direction.…”

“…5). A linear behavior in the in-plane hysteresis loops is indicative of the presence of a weak perpendicular anisotropy [32][33]10], and its enhancement reflects the increase of the out-of-plane component of the magnetization with the Tb content [23]. Considering the local range structural information, the out-ofplane component of magnetization seems to be related to the enhancement of TbFe 2 phase, because of the phase segregation promoted upon the increase of Tb.…”

“…Fe-Ga alloys appeared in 2000 as an option to TbFe 2 due to their lower coercivity and price, combined with a higher mechanical reliability and chemical stability together with a reasonably high  s of 440 ppm at room temperature [8][9]. The existence of PMA in Fe-Ga has also been reported, with particular features such as rotatable magnetic anisotropy [10][11][12].…”

In this work the authors present their investigation on sputtered [Fe72Ga28/Tb33Fe37]2 multilayers in which the Tb‐Fe thickness is kept fixed (50 nm), whereas the Fe‐Ga ranged from 25 to 100 nm. In particular, the authors have study the out of plane component of the magnetization by means of vibrating sample magnetometry and magnetic force microscopy. Samples are structurally characterized by X‐ray diffractometry and electron microscopy in order to correlate the magnetic characterization with the structural properties. In addition, the authors anneal the samples at 400 °C in order to analyze the effect of the thermal treatment on both, structural and magnetic properties. In the as‐grown samples, the out of plane component of the magnetization can be related to both, Tb‐Fe and Fe‐Ga. However, experimental results indicate that annealing reduces this component of the magnetization due to the crystallization of ordered phases in the Fe‐Ga layers.
