 Zusammenfassung: This work reports on the structural and magnetic properties of Mn2.7-xFexGa1.3 Heusler films with different Fe content x (0 <= x <= 1.2). The films were deposited heteroepitaxially on MgO single crystal substrates, by magnetron sputtering. Mn2.7-xFexGa1.3 films with the thickness of 35 nm were crystallized in a tetragonal D0(22) structure with (001) preferred orientation. Tunable magnetic properties were achieved by changing the Fe content x. Mn2.7-xFexGa1.3 thin films exhibit high uniaxial anisotropy K-u >= 1.4MJ/m(3), coercivity from 0.95 to 0.31 T, and saturation magnetization from 290 to 570 kA/m. The film with Mn1.6Fe1.1Ga1.3 composition shows high Ku of 1.47 MJ/m(3) and energy product (BH)(max) of 37 kJ/m(3) at room temperature. These findings demonstrate that Mn2.7-xFexGa1.3 films have promising properties for mid-range permanent magnet and spintronic applications. (C) 2017 Author(s).
