| Research Abstract |
(1) Sm-Fe thin films as giant magnetostrictive materials were prepared by d.c.magnetron sputtering process with mixed Ar-N_2 gas or Ar-CH_4 gas. The maximum value of magnetostrictive susceptibility of prepared thin films was showed at 1.0 vol% of N_2 and 0.5 vol% of CH_4.
(2) Supersaturated solid solution of Fe-In (Fe-In are immiscible system) thin films were prepared by the Ion-Plating process.
(3) The effect of ion bomberdment on the magnetostrictive characteristics of Tb-Fe and Sm-Fe films was quantitatively discussed by an ion bombardment parameter P_i. The ion bombardment parameter P_i could be applied to the design or modify the magnetostrictive susceptibility of films upon the film preparations.
