“…In the same systems there is a rapid change in the elastic contribution to enthalpy which maximizes over the same composition range where the amorphous phase is most expected. In the FeeV, FeeCr and in the FeeMo systems the difference in enthalpy is not so high [47,53] and the elastic contribution to enthalpy does not change drastically over composition. The chemical contribution to enthalpy as calculated by the same model for the Fe-ETM systems under consideration are given in Fig.…”

“…So far the crystallization is obtained by a subsequent thermal annealing 8 at typically 300 C, sometimes preceded by an in situ infrared annealing. 6 The Ta/CoFeB interface remains reasonably sharp because the solubility of Fe in Ta is very low 9 and that of Co in Ta is only a few percent. 10 The CoFeB/MgO interface is free of galvanic corrosion since Fe is more noble than Mg; experimentally, this interface gets sharper upon annealing 4,11 since O atoms initially incorporated in the transition metal due to the deposition conditions migrate to the MgO.…”

We study perpendicularly magnetized Ta/CoFeB/MgO films and investigate whether their irradiation with light ions can improve their properties by inducing a different crystallization dynamics. We report the magnetization, anisotropy, g-factor, and damping dependence upon irradiation fluence and discuss their evolutions with collisional mixing simulations and its expected consequence on magnetic properties. We show that after a short irradiation at 100 °C, the anisotropy increases close to the value obtained by conventional high temperature annealing. Higher irradiation-induced increase of anisotropy can be obtained but with a detrimental effect on the damping that can be understood from spin-orbit contributions.

“…Thirdly, the irradiation dose could be finely varied by adjusting the ion current density, thus enabling one to trace the detailed process in the non-equilibrium alloy formation. Till now, some 100 binary metal systems have been studied and a great number of non-equilibrium alloys have been obtained by IBM [11][12][13][14]. Meanwhile, in recent years, theoretical studies have also been performed to establish relevant model for explaining the formation of the non-equilibrium alloys.…”
