| Abstract(in English) | In order to clarify the relationship between lattice distortion and magnetic properties of Heusler alloy, the structural and magnetic properties of Fe_2VSi single layer and [Fe_2CrSi / Fe_2VSi]_5 artificial lattice deposited on Mg_2Al_2O_4substrate have been investigated. The lattice misfit between Fe_2YSi (Y = Cr, V) and MgAl_2O_4 is as small as 0.7%, and it is known that Fe_2CrSi and Fe_2VSi shows antiferomagnetism and ferromagnetism. The lattice distortion of Fe_2VSi films have been provided by using MgAl_2O_4 substrate and the Neel temperature (T_N) increases with decreasing c/a value. The maximum T_N of Fe2VSi on MgAl2O4substrate is 57% larger than bulk value. The saturation magnetization artificial lattice using ultra thin (1.4nm)Fe_2VSi layers is a little larger than Fe_2CrSi single layer. |
