FeGa alloys are among the most promising magnetostrictive materials. How to improve magnetostriction of has been a long-term concern. In this work, trace amount Pt doped FeGa-(Fe0.83Ga0.17)100–xPtx (x = 0, 0.2, 0.4, and 0.6) was fabricated using melt-spinning technique. The magnetostriction, crystal structure, magnetocrystalline anisotropy ribbon samples were studied, revealing that conforming between growth direction easy magnetization axis, enlarged lattice parameter both contribute...
FeGa-based alloys are potential candidates in magneto-mechanical transversion applications. It has been demonstrated that doping with certain elements results the increase λ100 and modification of texture, both which effectively enhance magnetostriction FeGa. However, contribution each factor is difficult to distinguish because lacking an effective physical model. In this work, based on independence saturation (λs) magnetic domain distribution, a paradigm combines orientation distribution...
By solving the Schrödinger and Poisson equations self-consistently for AlGaN/GaN QWs, we calculate intersubband optical absorption coefficients QWs with various well thicknesses. increasing thickness, amplitude of dipole matrix increases slowly. However, decrease energy separation results in red-shift resonant peak magnitude peak. Moreover, when thickness decreases to 10 Å, evident overlap between wave functions first two subbands leads abrupt These indicate that can be greatly modulated by...
