Magneto-Elastic and Mechanical Properties of Fe_81-xNi_xGa₁₉/Si(100) and Fe_81-yNi_yGa₁₉/Glass Films

Abstract:

Two series of Fe_81-xNi_xGa₁₉/Si (100) and Fe_81-yNi_yGa₁₉/glass films, where x or y = 0 26at.%Ni, were made by the magnetron sputtering method. We have performed three kinds of experiments on these films: the saturation magnetostriction (λ_S); [ii] the nanoindentation; and [iii] magnetic hysteresis-loop measurements. The main findings of this study are summarized below:[ λ_S reachesa local maximum, when x = 22 and [B] the Youngs modulus, E_f, of the Fe-Ni-Ga film deposited on a Si (100) substrate is larger than that (the same film) deposited on a glass substrate. We conclude thatthe Fe₅₉Ni₂₂Ga₁₉ film could beemployed in a low-field and low-costnano-magnetic switching device.
